- Downgrade expected race conditions to DEBUG level
- Auto-blacklist MAC addresses on connection failures
- Add diagnostic logging for concurrent connection tracking
BLE Driver changes:
- Add _connecting_peers set to track in-progress connections
- Prevent concurrent connection attempts to same address
- Attach cleanup callbacks to connection Futures
- Add defense-in-depth cleanup in finally blocks
- Detailed logging for connection state debugging
Documentation updates:
- Add deployment workflow documentation to README.md
- Update .github/workflows/README.md with CD workflow details
