Hardening Changes

The following targeted fixes were applied to harden the production environment without rewriting architecture:

1. Websocket Loop Fix: Copied active_connections before iteration to prevent RuntimeError.
2. Memory Trimming: Capped detections_history to 500 records to prevent memory growth.
3. Timer De-duplication: Replaced overlapping setInterval/setTimeout calls in useCommandApiStatus.
4. Unmount Cleanup: Added proper clearInterval to AlertFeed.jsx.
5. Debug Endpoints: Added /debug/vision and /debug/backend for runtime regression detection.
