* arch: decouple HTTP API gateway and MCP gateway via shared schema resolver
- Add gateway/schema: shared registry watcher and endpoint schema parser
used by both gateways, replacing duplicated discovery logic in gateway/mcp
- gateway/mcp: consume schema.Resolver; add NewServer for independent
lifecycle (discovery/watching in NewServer, transport in Serve, shutdown
via Stop)
- gateway/api: remove MCPEnabled/MCPAddress fields and background MCP
spawning; the HTTP gateway no longer starts MCP
- cmd/micro/run and cmd/micro/gateway: instantiate and orchestrate both
gateways explicitly, shutting down together on signal or first exit
- Mark gateway decoupling tickets 01-03 done
* feat(mcp): add streamable-HTTP transport for browser MCP clients
Implement the MCP streamable-HTTP spec at /mcp: POST JSON-RPC (batches,
notifications -> 202), GET SSE stream with heartbeat and session
lifecycle, DELETE session teardown, Mcp-Session-Id minted on initialize,
30-min idle session sweep. Tool dispatch shares invokeTool with the
legacy /mcp/call route; x402 challenge and tool-execution errors surface
as isError results.
Fixes browser-based clients (llama.cpp web UI): CORS preflight allows
mcp-protocol-version, and serveHTTP now shuts down the HTTP server when
the context is canceled so Ctrl-C/SIGTERM terminate cleanly.
