- Fix integer underflow panic in LED color publisher by adding bounds checking
- Reduce screenshot capture frequency from 15 FPS to 5 FPS for better CPU performance
- Reduce WebSocket force-send frequency from 200ms to 500ms
- Fix WebSocket resource leak by properly cleaning up streams when connections end
- Add proper stream lifecycle management with is_running flag checks
- Ensure background tasks exit when streams are stopped
This resolves the issue where CPU usage remained above 100% after visiting
the LED strip configuration page, even when navigating to other pages.
- Fix LED color publisher: uncomment display_colors_tx.send() to enable LED color events
- Replace rust_swift_screencapture with screen-capture-kit for better macOS compatibility
- Add bounds checking in LED color processing to prevent array index errors
- Update screenshot manager to use CGDisplay as fallback implementation
- Fix frontend screenshot URL protocol to use ambient-light://
- Add debug logging for LED color events in frontend
- Remove debug logs that were added for troubleshooting
- Update dependencies and remove CMake-dependent paho-mqtt temporarily
This resolves the issue where LED color events were not being sent to the frontend,
enabling real-time LED color visualization in the UI.
