Detailed Description
Background coroutine that publishes a heartbeat on a timer.
Embed one per domain service by co_spawning run() from the on_started callback in ores::service::service::run(). The heartbeat is received by the telemetry service which persists it to ores_telemetry_service_samples_tbl, enabling the service dashboard to show live RAG status for every running service instance.
A unique instance_id UUID is generated at construction time so that multiple instances of the same service can be tracked independently.

◆ run()
| boost::asio::awaitable< void > run | ( | ) |
Runs the heartbeat loop as an awaitable coroutine.
Publishes one heartbeat immediately on start, then repeats every interval_seconds. Exits cleanly when the io_context shuts down.
