- Replace raw BleakClient with establish_connection from
bleak-retry-connector (retries, GATT service cache, proxy-aware)
- Replace fragile asyncio.Event with asyncio.Queue for response frames,
drain stale data on each connection to prevent cross-cycle leakage
- Register BLE advertisement callback to keep BLEDevice reference fresh
across ESPHome proxy path changes
- Remove asyncio.sleep(2) device lookup hack
- Increase poll timeout floor from 10s to 20s
- Increase failure tolerance from 3 to 5 consecutive misses
- Bump default poll interval to 30s, min to 15s (halves connection churn)
