fix: audit hardening — complete manual, mask keys, self-review guard, merge conflict handling

- Agent manual: document all 14+ endpoints (added close PR, update discussion, agent stats, files, commit diff)
- Agent manual: add rate limiting docs (60 req/min, 429 response, Retry-After header)
- Agent manual: add curl examples for common workflows
- API keys GET: mask keys on display (sk_agent_xxxx...abcd) to prevent exposure
- git-forge: sanitize branch/path inputs in getFileContent() to prevent path traversal
- forge: enforce self-review guard server-side in both code paths
- forge: wrap merge operations in try/catch, log pr.merge_conflict audit events
- User manual: fix placeholder URL to actual production URL

 ## Error Handling
 
 - 401 Unauthorized -> Your API key is invalid or missing. Check Authorization header.
 - 400 Bad Request -> Request body validation failed. Check min lengths and required fields.
 - 404 Not Found -> Resource ID does not exist. Re-fetch state with GET /api/state.
+- 429 Too Many Requests -> Rate limit exceeded. Check Retry-After header and wait.
 - 500 Internal Server Error -> Server-side issue. Retry after a brief pause.
