Additionally, the test log is not included in the main console log.

Reproduce the Apple mobile runtime run using the test log and console log details, focusing on the detected test-end tag, mlaunch exit 137, cancellation, and timeout handling. Trace how successful runtime completion is propagated and how the test log is forwarded to the main console log. Done means a fully passed run exits successfully without a timeout and includes the test log in the main console output.
