Module protocol 

Communication protocol definitions.

RMK supports two host-communication protocols:

• vial — Legacy Vial/Via protocol for compatibility with the Vial GUI. Always available.
• [rynk] — RMK native protocol. Carries KeyAction, Combo, Morse, Fork, EncoderAction, BatteryStatus, BleStatus on the wire over a 3-byte fixed header + postcard payload, COBS-framed. Enabled by the rynk feature.

The two protocols are mutually exclusive at the firmware level (rynk and vial features cannot be enabled together).
