Add OrchestratorApiKeyGuard to protect agent management endpoints (spawn,
kill, kill-all, status) from unauthorized access. Uses X-API-Key header
with constant-time comparison to prevent timing attacks.
- Create apps/orchestrator/src/common/guards/api-key.guard.ts
- Add comprehensive tests for all guard scenarios
- Apply guard to AgentsController (controller-level protection)
- Document ORCHESTRATOR_API_KEY in .env.example files
- Health endpoints remain unauthenticated for monitoring
Security: Prevents unauthorized users from draining API credits or
killing all agents via unprotected endpoints.
