Research direction

Start with docker_helper.py lines 150:156 and the watch_container function, then trace the docker_container.logs(stream=True) call through the traceback. Compare the reported behavior with docker-py issue #188 and determine the expected handling for the missing container. Done means the WSL2 reproduction no longer produces the reported unhandled NotFound error.
