Asim Aslam 4311b73361 Enhance ADK vs Go Micro comparison and apply lint fixes (#2994)
* docs: compare Go Micro with Google ADK in the comparison guide

Adds a 'vs Agent Frameworks (Google ADK)' section: ADK builds an agent,
Go Micro builds the distributed system the agent lives in (agents are
services in the mesh). Covers the category difference, a feature table,
when to choose each, and MCP/A2A interoperability.

Claude-Session: https://claude.ai/code/session_01CmdEY7pYmV5zzwCjNJ4ykL

* docs: replace ADK comparison slogan with concrete explanation

State plainly what each tool provides (ADK builds an agent process; Go Micro
builds the surrounding service mesh) instead of marketing phrasing.

* lint: apply golangci-lint autofixes; exclude ST1003 and demo errcheck

Mechanical, behaviour-preserving fixes applied by 'golangci-lint run --fix':
gofmt, misspell (US spelling), usestdlibvars (http.Method*/Status*), unconvert,
and the auto-fixable staticcheck simplifications (QF*, S1017/S1019/S1023/S1039).

Config: exclude ST1003 (remaining offenders are exported API renames, e.g.
web.Id, which would break compatibility) and skip errcheck for examples/ and
internal/harness/ (demo code where fire-and-forget is intentional).

Build and test compilation verified.

* lint: WIP cleanup checkpoint (errcheck config + partial fixes)

Checkpoint of an in-progress golangci-lint cleanup (background pass). Builds
cleanly; lint is not yet zero. Follow-up commit will complete the cleanup and
switch CI to a blocking full-tree lint.

Asim Aslam ca87efef2f feat(agent): expose run metadata + structured guardrail reasons to tool wrappers (#2981)
goreleaser / goreleaser (push) Has been cancelled
Closes the remaining ask in #2980 without adding a parallel callback API.
ToolResult.Refused tags a guardrail block with a reason (ai.RefusedLoop /
RefusedMaxSteps / RefusedApproval) so a wrapper can switch on it instead of
parsing the message. ai.RunInfo (RunID, ParentID, Agent) rides on the
context passed to the tool handler, giving wrappers run correlation and
delegation lineage. Before/after/retry/failure were already covered by
AgentWrapTool; this adds the metadata. Docs + tests included.

Asim Aslam 5e5d253abd feat(agent): tool-execution wrappers via WrapTool (#2969)
Restructure ai.ToolHandler to the structured, ctx-carrying shape that
mirrors a go-micro RPC handler:

    func(ctx context.Context, call ai.ToolCall) ai.ToolResult

This reuses the existing ToolCall (with its correlation ID) and
ToolResult types instead of the flat (name, input)->(any, string)
signature, and adds ToolCall.Scan for typed argument access.

Add ai.ToolWrapper and the agent option WrapTool / micro.AgentWrapTool —
the tool-side analogue of client.CallWrapper and server.HandlerWrapper.
Reframe the built-in guardrails (MaxSteps, LoopLimit, ApproveTool) as
composed wrappers around a base handler; developer wrappers compose
outermost, so they observe every call and result, including refusals.

Update all provider call sites, the MCP server and chat handlers, the
integration harnesses, and docs to the new signature.

Asim Aslam d3c4981326 Enhance AI service generation with prompt-based architecture and logic (#2926)
goreleaser / goreleaser (push) Has been cancelled
* feat: add micro new --prompt and micro run --prompt

Add AI-powered service generation: describe a system in natural
language and get real go-micro services with proto definitions,
handlers, doc comments, and MCP support.

micro new --prompt "a contact book with notes and tags" \
  --provider anthropic

Generates:
  contacts/ — CRUD service with name, email, phone fields
  notes/    — notes linked to contacts
  tags/     — tagging system

Each service gets:
  proto/{name}.proto   — domain model + CRUD endpoints
  handler/{name}.go    — in-memory store, @example tags for MCP
  main.go              — MCP-enabled, proper imports
  go.mod + Makefile     — compiles with go mod tidy + make proto

micro run --prompt does the same then starts all services.

The LLM designs the architecture (service names, fields, endpoints,
descriptions) and returns structured JSON. Code generation uses
the existing template patterns — the output is standard go-micro
code that compiles, runs, and is immediately callable via MCP
and micro chat. No AI dependency at runtime.

* feat: LLM generates real business logic with compile-fix loop

Rebuild the generate package so the LLM writes actual handler
code with business logic, not just CRUD scaffolding.

The flow is now:
1. LLM designs architecture (service names, fields, endpoints)
   → returns structured JSON
2. Proto, main.go, go.mod, Makefile generated deterministically
   from the design (guaranteed to be correct)
3. go mod tidy + make proto compiles the protos
4. LLM generates handler code with REAL business logic
   → given the proto, endpoint descriptions, and go-micro patterns
5. go build — does it compile?
6. If no: feed errors back to LLM, get fixed code (up to 3 attempts)
7. If yes: service is ready

The handler prompt instructs the LLM to:
- Use sync.RWMutex for thread-safe in-memory state
- Include validation, edge cases, meaningful errors
- Write doc comments with @example tags for MCP
- Implement actual domain logic, not just map operations

Proto generation still uses deterministic templates (CRUD +
custom endpoints from the design spec) to guarantee correctness.
The compile-fix loop catches LLM mistakes automatically.

Both micro new --prompt and micro run --prompt use this flow.

* fix: handle edge cases in prompt-based generation

- Fix PATH for protoc-gen-micro in child processes
- Handle existing directories: skip structural files (main.go,
  go.mod, Makefile) if dir exists, always regenerate proto,
  only write placeholder handler if none exists
- Allow re-running micro new --prompt on same directory to
  iterate on business logic without clobbering user edits

Tested end-to-end: "a simple todo list with tasks and categories"
generates 2 services (task-service, category-service) with real
business logic (validation, toggle complete, etc.), compiles
after 1 fix iteration, and runs with 6 MCP tools discovered.

* feat: auto-detect modified handlers on regeneration

Instead of requiring a --keep-handlers flag, the generate package now
tracks a SHA-256 hash of each generated handler in a .micro metadata
file. On re-run, if the user has edited the handler since generation,
it's left untouched. Unmodified handlers are regenerated normally.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: add tests, fix go.mod, gitignore, proto tracking, spinner

- Add 12 tests covering helpers, proto generation, hash tracking
- Fix go.mod: write minimal module file, let go mod tidy resolve deps
- Add .gitignore to prompt-generated services
- Protect user-edited proto files (same hash tracking as handlers)
- Add spinner during LLM calls so it doesn't look hung

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: signal handling, existing service discovery, help text

- Ctrl+C during generation now cancels LLM calls immediately via
  signal-aware context; re-run picks up where it left off
- Design() scans for existing services in the working directory and
  includes their proto definitions in the prompt, so the LLM extends
  the system rather than redesigning from scratch
- Updated --prompt help text with usage examples on both new and run
- Listed all supported providers in flag descriptions
- Added discoverExisting test

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: show endpoints in run --prompt output, add micro chat hint

Print endpoint names and descriptions when designing services so users
see what was built. Add a micro chat hint to the run banner so users
know how to interact with their services after startup.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* fix: generated go.mod uses go 1.24 with explicit go-micro require

go 1.22 with no explicit require caused Go to resolve sub-packages
(gateway/mcp, client, server) as separate modules, hitting stale v1.18
tags. Pin to go 1.24 + require go-micro.dev/v5 v5.24.0 so go mod tidy
resolves all sub-packages from the root module correctly.

Tested end-to-end: 4 services generated and compiled successfully.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* fix: skip handler regeneration when proto unchanged

Compare proto hash before and after structure generation. If the proto
didn't change and the handler wasn't edited by the user, skip go mod
tidy, make proto, LLM handler generation, and compile-fix entirely.
Prints "(unchanged)" instead.

Reduces re-run of 4-service project from ~2 minutes to ~10 seconds.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: confirm design before generating code

Show the service design (names, endpoints) and prompt "Generate? [Y/n]"
before spending LLM time on handler generation. Applies to both
micro new --prompt and micro run --prompt. Default is yes (enter).

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* fix: use port :0 for MCP in generated multi-service projects

Each generated service had mcp.WithMCP(":3001") hardcoded, causing
port conflicts when running multiple services. Use :0 to auto-assign
a free port. micro run's central gateway handles unified MCP access.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: truncation detection, tool result display in chat

- Detect truncated LLM responses (unbalanced braces, doesn't end
  with '}') and retry with a conciseness hint before falling through
  to compile-fix
- Show tool call results in micro chat output (← for success, ✗ for
  errors) so users can see what the LLM did
- Add Result/Error fields to ToolCall, populated by Anthropic provider
  after tool execution
- Add isTruncated tests

Tested end-to-end with Anthropic: services generate, compile, start,
register, respond to RPC calls, and micro chat discovers and calls
tools correctly.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* fix: Anthropic tool loop, service naming, chat tool results

Anthropic provider:
- Fix tool execution loop to properly iterate (was re-processing all
  tool calls instead of only new ones each round)
- Clean assistant content blocks before sending back (strip 'id' from
  text blocks that Anthropic rejects on input)
- Include tools in follow-up requests so model can make additional calls
- Loop up to 10 rounds until model responds with text only

Service naming:
- Strip '-service' suffix from micro.New() name so services register
  as 'task', 'category' instead of 'taskservice', 'categoryservice'

Chat:
- Show tool results (← for success) and errors (✗) in chat output

Tested end-to-end: create task → list tasks works as multi-step
orchestration through micro chat with Anthropic Claude.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: blog post 13 — from prompt to production

Covers the full micro run --prompt flow: design, generate, compile-fix,
run, and chat orchestration. Positions agent-as-orchestrator as the
answer to service coordination.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* fix: timeouts, max_tokens, TTY detection, smaller services

- Add 60s timeout on design, 90s on handler generation, 60s on
  compile-fix LLM calls so hung providers don't block forever
- Bump Anthropic max_tokens from 4096 to 8192 to reduce truncation
- Add TTY detection: spinner prints static message in non-TTY (CI/pipes)
  instead of ANSI escape codes
- Tighten prompts: max 200 lines per handler, 2-4 services, 5-8 fields,
  explicit "services don't call each other" rule

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: chat suggests creating services when capabilities are missing

Update system prompt with the list of available services. When the user
asks for something no existing service can handle, the agent explains
what's available and suggests the exact micro new --prompt command to
create the missing service.

This is the natural evolution path: start with a few services, talk to
them via chat, and when the domain grows, the agent tells you what to
add. Each service stays small and focused.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: chat generates and starts services inline, drop -service suffix

Chat agent now has a micro_generate_service tool. When the user asks
for a capability that doesn't exist, the agent generates the service,
compiles it, starts it as a background process, waits for registration,
re-discovers tools, and uses the new endpoints immediately — all within
the conversation.

Service naming: design prompt now instructs LLM to return names without
'-service' suffix (e.g. 'task' not 'task-service'). buildMain keeps
TrimSuffix as safety net for backward compatibility.

Spawned processes are cleaned up when chat exits.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* docs: rewrite blog post 13 with inline service generation

Updated to reflect the full UX: services generate and start within
the chat conversation. Added the shipping example showing the agent
creating a service mid-conversation. Removed -service suffix from
all examples. Tightened the narrative around agent-as-orchestrator.

https://claude.ai/code/session_01QTp4SshuVmLAvvEGJe4TJd

* feat: persistent storage, README quickstart, auto-detect new services

Storage: generated handlers now use go-micro's store package instead
of in-memory maps. Data persists across restarts. The handler prompt
includes store API examples so the LLM generates correct store usage.

README: added "Generate From a Prompt" section with micro run --prompt
and micro chat examples, linking to blog post 13.

Watcher: micro run now scans for new service directories every 5s. When
micro chat generates a service, micro run detects the new directory,
builds it, starts it, and adds it to the watcher — fully automatic.
Added AddDir/Dirs methods to the watcher.

Blog: updated post 13 with persistent storage example and watcher note.

Asim Aslam 888dbbca4a Refactor AI tool handling and enhance CLI command documentation (#2920)
goreleaser / goreleaser (push) Has been cancelled
* refactor(ai): rename ToolSet to Tools, simplify wiring with WithTools

Move tool discovery/execution fully into the ai package as ai.Tools
(formerly ai.ToolSet), and simplify the usage model:

- NewTools(reg, ai.ToolClient(c)) takes the execution client as an
  option instead of threading it through Handler(c) per call
- New ai.WithTools(tools) option wires the tool handler into a model
  in one call, replacing ai.WithToolHandler(set.Handler(c))
- ai.DiscoverTools(reg) for one-shot discovery

Before:
  set := ai.NewToolSet(reg)
  list, _ := set.Discover()
  m := ai.New(p, ai.WithToolHandler(set.Handler(client)))

After:
  tools := ai.NewTools(reg, ai.ToolClient(client))
  list, _ := tools.Discover()
  m := ai.New(p, ai.WithTools(tools))

Update ai/flow, micro chat, README, ai integration doc, Atlas Cloud
guide, and blog posts 3/8/9/10.

* feat(cli): add per-interface commands (registry, broker, store, config)

Map go-micro's core interfaces onto the CLI so the framework's
building blocks are inspectable and manipulable from the terminal:

  micro registry list/get/watch       service discovery
  micro broker publish/subscribe      pub/sub messaging
  micro store read/write/delete/list  persistence
  micro config get/dump               dynamic config (from env)

Structured pluggably in cmd/micro/resource: each interface is one
file exposing a Command() func, all wired through a commandFuncs
slice in resource.go. Adding a new resource command is a single
file plus one slice entry. Shared printJSON/fail helpers keep
output and errors consistent across commands.

Each command's verbs mirror the interface methods. Output is JSON
for structured data, raw for single values. Update README and
getting-started with an "inspecting the framework" section.

* docs: update CLI README with all new commands

Add documentation for commands that were missing from the CLI README:
- micro new --template (crud, pubsub, api)
- micro api (standalone HTTP gateway)
- micro registry list/get/watch
- micro broker publish/subscribe
- micro store read/write/delete/list
- micro config get/dump
- micro chat (interactive LLM agent)
- micro flow run/exec (event-driven orchestration)
- micro mcp serve/list/test

Organized into sections: API Gateway, Inspecting the Framework
(registry, broker, store, config), and AI & Agents (chat, flow, mcp).

* refactor(ai): move History from caller to Request field

History is now pure state (no Generate method). Instead, pass it
via Request.History and call ai.Generate(ctx, model, req):

Before:
  hist := ai.NewHistory("system prompt", 50)
  resp, _ := hist.Generate(ctx, model, prompt, tools)

After:
  hist := ai.NewHistory(50)
  resp, _ := ai.Generate(ctx, model, &ai.Request{
      Prompt:       prompt,
      SystemPrompt: "system prompt",
      Tools:        tools,
      History:      hist,
  })

The model is always the thing you call. History is context you
pass in. ai.Generate() handles the bookkeeping: prepends
accumulated messages before the call, records the exchange after.

NewHistory no longer takes a system prompt (it belongs on the
Request, where it always did).

Update micro chat, ai/flow, and all blog posts/docs.

* refactor(ai): make History a plain message accumulator

History no longer has Generate or touches the model. It's just
Add/Messages/Reset/Len with truncation — a helper for building
Request.Messages across turns.

Before:
  hist := ai.NewHistory(50)
  resp, _ := ai.Generate(ctx, m, &ai.Request{History: hist, ...})

After:
  hist := ai.NewHistory(50)
  hist.Add("user", prompt)
  resp, _ := m.Generate(ctx, &ai.Request{Messages: hist.Messages(), ...})
  hist.Add("assistant", resp.Reply)

Remove History field from Request. Remove package-level
ai.Generate(ctx, model, req) wrapper — users call m.Generate()
directly, which is the interface method. History is a convenience
for accumulating messages, not a participant in generation.

Update micro chat, ai/flow, blog posts 9 and 10.

Asim Aslam 1e2901ad0e feat(ai): add ImageModel interface with Atlas Cloud and OpenAI support (#2905)
goreleaser / goreleaser (push) Has been cancelled
Add ai.ImageModel interface for text-to-image generation alongside
the existing ai.Model for text. Uses the same options pattern
(WithAPIKey, WithBaseURL) and the same provider registration
system (RegisterImage/NewImage).

Implement GenerateImage for Atlas Cloud and OpenAI providers via
the OpenAI-compatible /v1/images/generations endpoint. Default
image model is gpt-image-1. Responses return images as URL,
base64, or both depending on the provider.

Update Atlas Cloud blog post and integration guide with image
generation examples. Update ai/README.md with ImageModel docs.

Asim Aslam 081e375f29 Add AI provider integration guide and new providers support (#2900)
* docs: add AI provider integration guide and Supported AI Providers section

Add a step-by-step guide for AI infrastructure companies to implement
ai.Model and contribute a provider to go-micro. Covers the full
lifecycle: skeleton, tool call handling, tests, registration, and PR
checklist.

Add a "Supported AI Providers" section to the project README that lists
current providers (Anthropic, OpenAI) in a table and links to the
integration guide with a call-to-action for new providers and sponsors.

Streamline the "Adding a New Provider" section in ai/README.md to point
to the new guide instead of duplicating a full code listing.

* fix: remove nonexistent Discord link from README

* fix(website): set content container width to 800px on desktop

Move the 800px max-width from .markdown-body up to .content so
the entire content pane (not just the inner body) is sized
correctly. The container now fills up to 800px beside the sidebar.

* feat(ai): wire Atlas Cloud into server and auto-detection

Import atlascloud provider in the micro server so it is available
when running micro run / micro server. Add atlascloud to
AutoDetectProvider so --ai_base_url with an atlascloud domain
selects the right provider automatically.

* feat(ai): add Google Gemini provider

Add ai/gemini implementing ai.Model for Google's Gemini API. Uses
the native generateContent endpoint with system_instruction,
contents/parts, and functionDeclarations — not an OpenAI shim.
Default model gemini-2.5-flash, auth via x-goog-api-key header.

Wire into micro server imports and AutoDetectProvider (matches
googleapis.com and google in base URL).

Update README.md and ai/README.md with provider listing.

* feat(ai): add Groq, Mistral, and Together AI providers

Add three new OpenAI-compatible providers:

- ai/groq: ultra-fast inference, default model llama-3.3-70b-versatile
- ai/mistral: Mistral AI, default model mistral-large-latest
- ai/together: Together AI, default model Llama-3.3-70B-Instruct-Turbo

All three are wired into the micro server imports and
AutoDetectProvider. README and ai/README updated with the full
provider table.

* feat(ai): add ai/tools helper and 'micro chat' interactive agent

Extract the registry-discovery + RPC-execution loop from the web
agent playground into a reusable ai/tools package:

- tools.New(reg) creates a Set bound to a registry
- Set.Discover() walks the registry and returns []ai.Tool with
  LLM-safe (underscored) names, remembering the mapping back to
  the original dotted form
- Set.Handler(client) returns an ai.ToolHandler that resolves
  the safe name and issues the RPC

Add cmd/micro/chat — an interactive 'micro chat' REPL that uses
ai/tools to let users talk to their services through any
registered AI provider. Supports --prompt for single-shot use,
auto-detects the provider from --base_url, and falls back to the
provider's conventional env var (ANTHROPIC_API_KEY, etc).

Update README with the new command and the programmatic example.

* feat(examples): add gRPC interop example

Add examples/grpc-interop showing that any standard gRPC client can
call a go-micro service — no go-micro SDK required on the client
side. Includes:

- proto/greeter.proto with generated Go, gRPC, and micro stubs
- server/ using go-micro gRPC transport
- client/ using stock google.golang.org/grpc (no go-micro imports)
- README with Python example and explanation of how routing works

Addresses the confusion from issue #2818 where users didn't know
that go-micro gRPC services are callable by any gRPC client.

Asim Aslam 76bfeae456 Claude/update docs roadmap f zd2 j (#2880)
* docs: update all four documentation guides and mark Q2 complete

- ai-native-services: add WithMCP one-liner, standalone gateway,
  WebSocket client example, and OpenTelemetry observability section
- mcp-security: add OTel distributed tracing, WebSocket authentication
  (connection-level and per-message), DeniedReason audit field
- tool-descriptions: add manual overrides with WithEndpointDocs and

- agent-patterns: add LangChain/LlamaIndex SDK pattern and standalone
  gateway production pattern with Docker example
- Update roadmap: mark Q2 documentation as complete, Q2 at 100%
- Update status: reflect all recent completions, shift priorities

https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc

* feat: add agent demo example and blog post

Add examples/agent-demo with a multi-service project management app
(projects, tasks, team) that demonstrates AI agents interacting with
Go Micro services through MCP. Includes seed data and example prompts.

Add blog post 4 "Agents Meet Microservices: A Hands-On Demo" walking
through the example code and showing cross-service agent workflows.

https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc

* feat: enable multiple services in a single binary

Remove global state mutations from service and cmd option functions so
that configuring one service no longer overwrites another's settings.

Key changes:
- service/options.go: remove all DefaultXxx global writes from option
  functions; newOptions() now creates fresh Server, Client, Store, and
  Cache per service while sharing Registry, Broker, and Transport
- cmd/cmd.go: newCmd() uses local copies instead of pointers to package
  globals; Before() no longer mutates DefaultXxx vars
- cmd/options.go: remove global mutations from all option functions
- service/service.go: export ServiceImpl type for cross-package use
- service/group.go: new Group type for multi-service lifecycle
- micro.go: add Start/Stop to Service interface, expose Group and
  NewGroup convenience function
- examples/multi-service: working example with two services

* feat: unify service API and clean up developer experience

- Unified service creation: micro.New("name", opts...) as canonical API
- Clean handler registration: service.Handle(handler, opts...) accepts
  server.HandlerOption args directly, no need to reach through Server()
- Unexported serviceImpl: users interact through Service interface only
- Service groups use Service interface (not concrete type)
- Fixed Stop() to properly propagate BeforeStop/AfterStop errors
- Fixed store init: error-level log instead of fatal on init failure
- Updated all examples to use consistent patterns
- Updated README, getting-started, MCP docs, and guides
- Added blog post about the DX cleanup

* fix: add blog post 5 to blog index

Blog post 5 (Developer Experience Cleanup) existed as a file but was
missing from the blog index page.

* refactor: rename model/ package to ai/ for AI model providers

The model/ package name conflicted with the conventional use of "model"
for data models. Renamed to ai/ which better describes the package's
purpose (AI provider abstraction for Anthropic, OpenAI, etc.) and frees
up model/ for future data model layer use.

- Rename model/ → ai/ with package name change
- Update all Go imports from go-micro.dev/v5/model to go-micro.dev/v5/ai
- Update cmd/micro/server/server.go references (model.X → ai.X)
- Update all documentation and roadmap references
- All tests pass, CLI builds successfully

* feat: add model package for typed data access with CRUD and queries

New model/ package provides a typed data model layer using Go generics.
Supports structured CRUD operations, WHERE filters, ordering, pagination,
and automatic schema creation from struct tags.

Three backends:
- memory: in-memory for development and testing
- sqlite: embedded SQL for dev and single-node production
- postgres: full PostgreSQL for production deployments

Key features:
- Generic Model[T] with Create/Read/Update/Delete/List/Count
- Query builder: Where(), WhereOp(), OrderAsc/Desc(), Limit(), Offset()
- Struct tags: model:"key" for primary key, model:"index" for indexes
- Auto table creation from struct schema
- 19 tests passing across memory and sqlite backends

* feat: add model code generation to protoc-gen-micro

Extend the micro plugin to generate model structs from proto messages
annotated with // @model. Generated alongside client/server code in
the same .pb.micro.go file.

For a proto message like:
  // @model
  message User { string id = 1; string name = 2; }

Generates:
- UserModel struct with model:"key" and json tags
- NewUserModel(db) factory returning *model.Model[UserModel]
- UserModelFromProto(*User) *UserModel converter
- (*UserModel).ToProto() *User converter

Supports @model(table=custom_table, key=custom_field) options.
Adds GetComments() to generator for plugin comment inspection.

* feat: add Model() to Service interface for Client/Server/Model trifecta

Every service now exposes Client(), Server(), and Model() — call services,
handle requests, and save/query data from the same interface. Includes
README docs, blog post, and a full model guide on the docs site.
