Fixes #1397

Summary

Implements production-ready lifecycle management with graceful shutdown and comprehensive health monitoring.

Changes

Health Check Endpoints

/health/detailed - Comprehensive health check with all service statuses (returns 200 for healthy, 503 for degraded/unhealthy)
/ready - Readiness probe for Kubernetes/Docker (returns 503 during startup or shutdown)
/live - Liveness probe with shutdown awareness (returns 503 after shutdown timeout)
/health/shutdown - Debug endpoint for shutdown status

Graceful Shutdown

Signal handlers for SIGTERM/SIGINT in lifespan manager
Thread-safe shutdown state tracking (request_shutdown(), is_shutting_down())
Readiness probe returns 503 during shutdown to stop new traffic
Liveness probe detects shutdown timeout for forced restart
Proper cleanup of background tasks and connections

Acceptance Criteria

Graceful shutdown implemented for all services
Health check endpoints respond with proper status codes
Readiness probe indicates when service is ready for traffic
Liveness probe detects when service needs restart
Signal handling works in container environments

Testing

All unit tests pass (966 passed)
Added comprehensive tests for new endpoints
Signal handlers gracefully degrade in non-main threads (test environment)

Implements production-ready lifecycle management with graceful shutdown
and comprehensive health monitoring:

Health Check Endpoints:
- /health/detailed - Comprehensive health with service statuses (200/503)
- /ready - Readiness probe for Kubernetes/Docker
- /live - Liveness probe with shutdown awareness
- /health/shutdown - Debug endpoint for shutdown status

Graceful Shutdown:
- Signal handlers for SIGTERM/SIGINT in lifespan manager
- Thread-safe shutdown state tracking
- Readiness probe returns 503 during shutdown
- Liveness probe detects shutdown timeout
- Proper cleanup of background tasks and connections

Acceptance Criteria:
✓ Graceful shutdown implemented for all services
✓ Health check endpoints respond with proper status codes
✓ Readiness probe indicates when service is ready for traffic
✓ Liveness probe detects when service needs restart
✓ Signal handling works in container environments
