Register the worker with PipelineRunner.add_workers() before calling run() instead. The worker argument still works but now emits a DeprecationWarning and will be removed in a future release. Update the runner docstrings, the run_test() helper, and all examples (including the asyncio.gather() forms) to use the new pattern.
