Ole-Morten Duesund 36722940eb feat(httpserver,log): /healthz, graceful shutdown, slog constructor 
Implements internal/httpserver and internal/log.

httpserver (forgejo-mcp-broker-8ei):
- Server struct owns the HTTP lifecycle; Run(ctx) blocks, Handler() returns
  the composed handler for unit tests
- GET /healthz returns JSON with status, version, git_revision, build_date,
  and store probe result. Returns 503 when the store reports unhealthy
- Signal handling delegated to the caller via ctx cancellation — main wires
  signal.NotifyContext, httpserver just responds to Done()
- Graceful shutdown with a configurable deadline (default 10s). When the
  deadline expires, falls back to http.Server.Close() so lingering
  connections are forcibly terminated — http.Server.Shutdown alone never
  interrupts active connections
- ExtraHandler extension point for the OAuth + MCP routes that land in
  phase 2 and phase 5, so the server doesn't need to be re-plumbed later

log:
- Small slog wrapper: New(w, debug) returns a JSON logger that stamps every
  record with service/version/git_rev for correlation across deployments
- Discard() helper for tests

Tests: 97.9% coverage on httpserver (all health states, wrong-method,
ExtraHandler dispatch, ctx-cancel shutdown, shutdown-deadline force-close
of hanging requests, missing-field errors), 100% on log.

Closes forgejo-mcp-broker-8ei.

forgejo-mcp-broker

OAuth 2.1 authorization server and MCP session broker for forgejo-mcp.

Lets MCP clients such as Claude.ai connect to a Forgejo instance through a single public HTTPS endpoint, with per-user authentication delegated to Forgejo's own OAuth2 provider. The broker handles the OAuth dance, then spawns a dedicated forgejo-mcp --transport stdio subprocess for each authenticated session, scoped to the authenticated user's Forgejo access token.

Status: Planning. No code yet. See docs/design.md for the architecture and docs/plan.md for the phased implementation plan.

How it fits

Claude.ai ──HTTPS──▶ Caddy ──▶ fjmcp-broker ──stdio──▶ forgejo-mcp  ──▶ Forgejo API
                                  (this)              (one per user     (per-user
                                                       session)          token)
  • fjmcp-broker (this project): one long-running process. Handles OAuth discovery, dynamic client registration, the authorization-code flow against Forgejo, session lifecycle, and stdio-to-streamable-HTTP bridging.
  • forgejo-mcp (existing project): used as-is. Spawned per-session with the authenticated user's FORGEJO_ACCESS_TOKEN in the environment.
  • Caddy: terminates TLS for the public hostname and reverse-proxies to the broker.

Why a broker instead of adding OAuth to forgejo-mcp?

Process-level isolation. Each user's Forgejo token lives in exactly one subprocess — the broker never needs to demultiplex tokens inside a single shared client. This keeps forgejo-mcp's sync.Once singleton-client pattern valid and avoids a refactor of every tool handler. Full trade-off in docs/design.md.
