Ole-Morten Duesund d16b18ea38 feat(oauth): authorization-server endpoints (forgejo-mcp-broker-pur)
Implements internal/oauth, the broker's OAuth 2.1 AS surface that
Claude.ai (and other MCP clients) talk to. User authentication is
delegated to upstream Forgejo via internal/forgejo.

Endpoints:
  POST /oauth/register   — RFC 7591 dynamic client registration
  GET  /oauth/authorize  — RFC 6749 + 7636 PKCE (S256 only)
  GET  /oauth/callback   — Forgejo redirects back here after consent
  POST /oauth/token      — authorization_code + refresh_token grants
  POST /oauth/revoke     — RFC 7009

Security model:
- PKCE required, S256 only — plain method rejected per OAuth 2.1
- Every broker-issued access/refresh token stored as hex(sha256(plain));
  plaintext leaves the broker exactly once in the /token response body
- Refresh-token rotation: each refresh issues a new token pair and
  revokes the old refresh (RFC 6749 §10.4)
- Auth-code single-use enforced atomically via UPDATE...WHERE used_at IS
  NULL with rows-affected check, blocking the concurrent-replay race
- Issuer URL sourced from cfg.Issuer at construction time, never from
  inbound headers — prevents host-header injection on /.well-known
  metadata that ships in 2d
- redirect_uri must match a registered URI exactly (no prefix/wildcard)

Pending-authorization state (between /authorize and /callback) lives in
an in-memory sync.Map with a 1-minute reaper goroutine. A broker restart
drops them, forcing the user to re-authorize — acceptable trade-off
versus introducing a fifth table.

Tests: 81.0% coverage with ~20 cases across happy paths, every required-
field error, PKCE failure, code-replay, refresh expiry/revocation,
client-id and redirect-uri mismatches, Forgejo-side errors, and the
reaper logic itself (internal test).

Closes forgejo-mcp-broker-pur. The OAuth keystone is in place; phase 2c
unblocks discovery (2d) and security review (2e), and combined with the
existing supervisor + bridge it unblocks the session glue work in
phase 5.

Beads - AI-Native Issue Tracking

Welcome to Beads! This repository uses Beads for issue tracking - a modern, AI-native tool designed to live directly in your codebase alongside your code.

What is Beads?

Beads is issue tracking that lives in your repo, making it perfect for AI coding agents and developers who want their issues close to their code. No web UI required - everything works through the CLI and integrates seamlessly with git.
