fix(ble): Add scanner-connection coordination to prevent "InProgress" errors

Browse source 
Scanner was calling BleakScanner.start() during active connection attempts,
causing BlueZ "Operation already in progress" errors. This fix adds coordination
between scanner and connection operations:

- Add _should_pause_scanning() method to check for active connections
- Modify _perform_scan() to skip scan cycle when connections in progress
- Scanner automatically pauses when _connecting_peers is not empty
- Scanner automatically resumes when connections complete

Impact:
- Eliminates scan-induced connection failures
- Reduces BlueZ error log spam
- Improves overall connection reliability

Files changed:
- src/RNS/Interfaces/linux_bluetooth_driver.py: Add pause logic
- tests/test_scanner_connection_coordination.py: Add test coverage
- BLE_PROTOCOL_v2.2.md: Document scanner coordination
- CHANGELOG.md: Record fix details
