- Add TimemoreScale implementation (Service FFF0, Notify FFF1, Write FFF2) - Protocol uses CRC-16/MODBUS checksum on all commands - Matches devices advertising name prefix 'Basic3 Link' - Register in DeviceImplementation, DeviceMatcher, DeviceFactory Protocol reverse-engineered from HCI snoop logs (12/12 verified).

Rework TimemoreScale to use the official framed protocol instead of hardcoded byte sequences: - Generic frame builder: A5 5A | opcode | cmd | length(2,BE) | data | crc - CRC-16/MODBUS auto-computed per frame - Notify parsing now reads Int32 BE weight, Int16 BE flow, UInt16 BE timer from the 0x01/0x01 stream frame (length 0x0009) - Populate ScaleSnapshot.flow and timerValue from the scale's own fields - Query battery on connect and report batteryLevel in snapshots - Tare/timer commands rebuilt via frame(opcode, cmd, data)
