Implements fcntl.flock() based locking for serial transport to prevent
USB serial conflicts when collect_companion and collect_repeater run
simultaneously. This addresses Ofelia's limitation where no-overlap
only prevents a job from overlapping with itself, not other jobs.
Key changes:
- Add connect_with_lock() async context manager to meshcore_client.py
- Use non-blocking LOCK_NB with async polling to avoid freezing event loop
- Only lock for serial transport (TCP/BLE don't need it)
- 60s timeout with clear error message if lock cannot be acquired
- Update collector scripts to use new context manager
- Remove external flock from cron examples (now handled in Python)
