Pull request overview
This PR adds explicit classification for broker acknowledge “404 / Job not found” responses and uses that classification to let single-use runners (ephemeral / --once) exit cleanly instead of continuing to poll in a terminal condition.
Changes:
- Add a new
RunnerRequestJobNotFoundExceptionand throw it fromBrokerHttpClient.AcknowledgeRunnerRequestAsyncwhen the broker returns a “Job not found” 404. - Update the listener runner loop to exit early for single-use runners when acknowledge hits the job-not-found terminal condition, while preserving best-effort behavior for persistent runners.
- Add L0 coverage for the new broker classification and the single-use vs persistent runner behaviors.

should this merge with the switch above somehow? since they are both kind of checking the brokererror and throw exception.

Can you help me understand more about this?
Is there an error kind we could rely on, instead of message?
I'm worried relying on the error message might be fragile. That's why error kind exists.

Good point, let me have a look at the API.
