Operators can now see recent mcpd error/fatal logs without kubectl:
- mcpd tees level>=error pino records into an in-memory ring buffer
(src/mcpd/src/services/error-log-buffer.ts; wired via pino.multistream in
server.ts so stdout logging is unchanged). Captures structured errors incl.
fatal kinds like BACKEND_TOKEN_DEAD.
- GET /api/v1/logs/errors?limit=N (RBAC: 'logs' operation).
- CLI: 'mcpctl errors [-n N]' renders TIME/LEVEL/DETAIL, most-recent-first.
Buffer unit tests (6); full suite 2223 passing. Needs a deploy to go live.
