- internal/auth/jwt.go: JWTValidator via lestrrat-go/jwx/v2, JWKS auto-refresh
- internal/auth/bearer.go: replace Gitea PAT validation with JWT->static->default chain
- internal/gitea/client.go: always use service PAT; remove TokenFromContext lookup
- internal/config/config.go: add DexIssuerURL, MCPAudience, MCPResourceURL, StaticToken
- cmd/gitea-mcp/main.go: wire validator, fix /.well-known to return real AS list
- bearer_test.go: rewrite for new API
claude.ai connectors call the server with no Authorization header (confirmed
via request logging). Add a configurable default Gitea PAT so unauthenticated
clients (like claude.ai) can still reach the server.
Claude Code continues to pass per-request PATs; defaultToken="" preserves
the existing strict behaviour when the env var is unset.

Callers now supply their own Gitea PAT as a Bearer token; the server validates
it against GET /api/v1/user and threads it through context to all downstream
Gitea API calls. GITEA_API_TOKEN env var and the GiteaAPIToken config field are
removed.
