Refactor agent plan storage, update docs, and release v6 (#2977 )

* test(harness): read agent plan from the scoped store

The store-scoping change moved an agent's plan from the default table
key agent/{name}/plan to its own table (database "agent", table {name},
key "plan"). The plan-delegate harness tests still read the old key and
failed with 'not found'; read through store.Scope(mem, "agent", name)
like the agent does.

* docs: orient agents-first across README, landing, and docs overview

Lead with agents (then services and flows), surface MCP + A2A as the
interop story, and frame agents as services. Landing hero and feature
grid reordered agents-first with an A2A gateway card.

* v6: module path go-micro.dev/v6, TLS secure by default, NewService

Cut v6. Three breaking changes, bundled so the major bump is paid once:

- Module path go-micro.dev/v5 -> go-micro.dev/v6 across all imports + go.mod.
- TLS verification on by default (was off). MICRO_TLS_SECURE removed;
  MICRO_TLS_INSECURE=true opts out for self-signed/dev.
- micro.NewService(name, opts...) is the canonical service constructor,
  symmetric with NewAgent/NewFlow; micro.New kept as a deprecated alias;
  the old name-less NewService(opts...) removed. Generators emit NewService.

Also ports the JWT auth token provider in-module (go-micro.dev/v6/auth/jwt/token
on golang-jwt/jwt/v5), dropping the v5-pinned github.com/micro/plugins/v5/auth/jwt
and the deprecated dgrijalva/jwt-go.

Docs/README/landing updated to v6 and @latest; v5->v6 migration guide added;
CHANGELOG cut as [6.0.0]. Blog posts left at their historical versions.

Broker

The broker provides pub/sub messaging for Go Micro services.

Features

Publish messages to topics
Subscribe to topics
Multiple broker implementations

Implementations

Supported brokers include:

HTTP (default)
NATS (go-micro.dev/v6/broker/nats)
RabbitMQ (go-micro.dev/v6/broker/rabbitmq)
Memory (go-micro.dev/v6/broker/memory)

Plugins are scoped under go-micro.dev/v6/broker/<plugin>.

Configure the broker in code or via environment variables.

Example Usage

Here's how to use the broker in your Go Micro service:

package main

import (
    "go-micro.dev/v6"
    "go-micro.dev/v6/broker"
    "log"
)

func main() {
    service := micro.NewService()
    service.Init()

    // Publish a message
    if err := broker.Publish("topic", &broker.Message{Body: []byte("hello world")}); err != nil {
        log.Fatal(err)
    }

    // Subscribe to a topic
    _, err := broker.Subscribe("topic", func(p broker.Event) error {
        log.Printf("Received message: %s", string(p.Message().Body))
        return nil
    })
    if err != nil {
        log.Fatal(err)
    }

    // Run the service
    if err := service.Run(); err != nil {
        log.Fatal(err)
    }
}

Configure a specific broker in code

NATS:

import (
    "go-micro.dev/v6"
    bnats "go-micro.dev/v6/broker/nats"
)

func main() {
    b := bnats.NewNatsBroker()
    svc := micro.NewService(micro.Broker(b))
    svc.Init()
    svc.Run()
}

RabbitMQ:

import (
    "go-micro.dev/v6"
    "go-micro.dev/v6/broker/rabbitmq"
)

func main() {
    b := rabbitmq.NewBroker()
    svc := micro.NewService(micro.Broker(b))
    svc.Init()
    svc.Run()
}

Configure via environment

Using the built-in configuration flags/env vars (no code changes):

MICRO_BROKER=nats MICRO_BROKER_ADDRESS=nats://127.0.0.1:4222 go run main.go

Common variables:

MICRO_BROKER: selects the broker implementation (http, nats, rabbitmq, memory).
MICRO_BROKER_ADDRESS: comma-separated list of broker addresses.

Notes:

NATS addresses should be prefixed with nats://.
RabbitMQ addresses typically use amqp://user:pass@host:5672.
