Use TimeoutExpired.stdout to capture partial output before timeout. Generate fallback XML if no output captured (hung containers). Prevents empty output for timed-out tests.

Good catch. Done. Good thing I didn't restart the agent-scalers after deploy.

I don't have a strong opinion here, but should we first try to terminate() the process (sends SIGTERM) and then send the kill() (sends SIGKILL) if it doesn't terminate after a fixed amount of time? That should give the process some additional time to write the logs before shutting down.

Already deployed and doesn't seem to break anything.
