Remove debug logging from BLE connection fix

User confirmed BLE connection is working correctly after the byte
counter fix, but reported slower performance compared to 8.0.1.

Analysis showed 4 console.log() statements in the data path:
- 2 logs on every BLE notification received (hot path)
- 2 logs during listener add/remove (cold path)

The hot path logs were causing performance degradation as they
execute on every 20-byte BLE packet received. Removed all 4
debug logs as they were marked TODO for removal after testing.

The core fix (using _onReceiveListeners array) remains intact.
