_isRunning was never cleared on the timeout path, so a single timed-out run locked the app out of starting another until it was restarted. It is now cleared in a finally block covering all three exits. Output was buffered inside the service and only handed over once the run finished, so the UI showed nothing until the end despite the native layer streaming line by line. The service republishes each line on outputLines and the view model appends to a transcript as they arrive. The channel handler was re-registered on every run and dereferenced _runCompleter with `!`, which threw once a late callback arrived after the field had been nulled. It is registered once in the constructor and reads the completer through a local. Also drops the duplicated argument list in favour of TestConfiguration.toCliArgs(), so the flags the UI sends have one definition. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
