- Log node_id hint in request_traceroute instead of silently dropping it
- Replace asyncio.shield/wait_for pattern with _wait_or_stop() to prevent orphan tasks on retry delays
- Poll _stop_event every 1s in _do_connect keep-alive loop to handle stop() race before _asyncio_stop is set
- Extract pubkey_prefix/sender_id in _on_channel_msg instead of hardcoding "unknown"
- Close coroutine and log in _submit() when worker is not running to prevent ResourceWarning
- Cap battery_pct at 100 to prevent values exceeding 100%

Implements AsyncWorker — the daemon asyncio thread that owns the meshcore
library connection, subscribes to all relevant EventTypes, and feeds events
back into MeshcoreClient via on_message/on_node/on_telemetry/on_traceroute/
on_connected/on_error. Includes retry-with-backoff (3 attempts: 5s/15s/45s),
thread-safe send_text/request_traceroute/scan_ble_sync for Flask callers,
and a standalone _scan_ble() coroutine using bleak.BleakScanner.
