Description

If a run has a profile flag enabled in options (or if the worker is started in profile mode), it should send out a special event at the end of a run with stats

This at the moment is really just related to messaging:

  • For each message emitted by the worker, how long did it take for lightning to reply

This needs to be a dedicated run:stats event, not part of run:complete, because it might be big. Lightning might need to know to keep the socket open if it's expecting run stats

Research direction

Start by tracing the worker's run-completion flow and the code that emits messages and receives Lightning replies. Confirm how profile mode is enabled, then define the dedicated run:stats event with per-message reply durations and verify that it is emitted only for profiled runs without being folded into run:complete.
