Detailed Description

Heartbeat Service — C++ SERVER_HEARTBEAT broadcaster.

Subscribes to Elodin [0x5000] (SequencerState) for current state, maps it to the legacy EngineState enum (0-4), and broadcasts SERVER_HEARTBEAT (type 2) to all boards on the subnet every 1s.

Packet: type(1)=2, version(1)=0, timestamp_ms(4 LE), engine_state(1)

Usage: ./heartbeat_service [–config PATH] [–elodin-host HOST] [–elodin-port PORT] [–broadcast-ip IP] [–broadcast-port PORT] [–interval-ms MS]
