- Add GracefulShutdown struct with watch channel for shutdown signaling - Handle SIGTERM/SIGINT via signal-hook to trigger graceful shutdown - Handle SIGHUP via signal-hook for config reload (same code path as admin socket) - Implement graceful shutdown sequence: stop accepting -> drain -> force-close -> cancel tasks -> exit 0 - Wire up main.rs with full server startup (health check, admin socket, HTTP redirect, HTTPS proxy) - Add integration tests for GracefulShutdown and SIGHUP reload - shutdown_timeout_secs configurable in StaticConfig (default 30)
