* Initial plan
* Add MCP per-tool scopes, tracing, rate limiting, and audit logging
- Add Scopes field to Tool struct for per-tool scope requirements
- Add Auth (auth.Auth) integration to Options for token inspection
- Add trace ID generation (UUID) propagated via metadata to downstream RPCs
- Add per-tool rate limiting with configurable requests/sec and burst
- Add AuditFunc callback for immutable tool-call audit records
- Extract tool scopes from registry endpoint metadata ("scopes" key)
- Update both HTTP and stdio transports with auth/trace/rate/audit
- Add comprehensive tests for all new functionality

* Revert unrelated example go.mod changes
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Remove auto-generated example go.sum files
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Add WithEndpointScopes helper, gateway-level ToolScopes, and documentation
- Add server.WithEndpointScopes() for declaring per-endpoint auth scopes at
handler registration time
- Add mcp.Options.ToolScopes for gateway-level scope overrides without
changing individual services
- Update documented example to show WithEndpointScopes usage
- Update examples/mcp/README.md with scopes, tracing, and rate-limiting docs
- Update gateway/mcp/DOCUMENTATION.md with scopes section and FAQ
- Add tests for both new features

* Fix ToolScopes doc comment: clarify override (not merge) semantics
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Revert unrelated example go.mod/go.sum changes
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Rename ToolScopes to Scopes in MCP Options
The field name "Scopes" is more universal and consistent with how
auth scopes are used throughout go-micro. Updated all code references,
tests, and documentation.

Major Features:
- Unified gateway architecture (micro run + micro server use same code)
- MCP (Model Context Protocol) integration as library package
- AI-accessible microservices with 3 lines of code
Gateway Unification:
- Created reusable gateway module (cmd/micro/server/gateway.go)
- Updated micro run to use unified gateway (removed duplicate code)
- Conditional authentication (disabled in dev, required in prod)
- Reduced code duplication, simplified maintenance
MCP Integration:
- New library package: gateway/mcp
- Automatic service discovery → MCP tools
- HTTP/SSE transport support (stdio coming soon)
- Works for both library users and CLI users
- CLI flags: --mcp-address for micro run and micro server
Documentation:
- ADR-010: Unified Gateway Architecture
- CLI & Gateway Guide for users
- MCP Gateway README and examples
- Blog post: Making Your Microservices AI-Native with MCP
Breaking Changes: None (fully backward compatible)
