fix: ADC notifications no longer emit 'status' (prevents timer jump)

- ADC (17-byte) now emits 'adc' + 'battery' events, not 'status'
- Fixes CRITICAL timer jump: remaining_ms:0 was resetting countdown
- Drop ADC packets with bad XOR checksum
- treating.js + index.js subscribe to 'battery' for live battery updates
- onStatus only updates remaining_ms when > 0
