Detailed Description

Stacklight Service — C++ STACKLIGHT_COMMAND sender.

Subscribes to Elodin [0x5000] (SequencerState) for current state, maps it to a StacklightCommandPacket (red/yellow/green/buzzer), and sends it via UDP unicast to the stacklight board whenever the state changes (plus a periodic keepalive resend).
