fix: Address GitHub Copilot review feedback
Resolved all 7 issues identified in PR review:
1. @testing-library/dom peer dependency already explicitly listed
2. Removed invalid eslint-disable comments (replaced with correct rule)
3. Fixed unstable callbacks in useMachinePolling using refs to prevent unnecessary re-renders
4. Fixed useAutoScroll options dependency with useMemo for stability
5. Fixed stale closure in BluetoothDevicePicker using functional setState
6. Fixed memory leak in useBluetoothDeviceListener by preventing re-registration of IPC listeners
7. Added proper eslint-disable for intentional setState in effect with detailed comment
All tests passing (91/91), build successful, linter clean.
