openenv-base image has no `uvicorn` command

[pro-wh]

$ docker run --rm ghcr.io/meta-pytorch/openenv-base:sha-562b545 uvicorn --version
docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: exec: "uvicorn": executable file not found in $PATH

Run 'docker run --help' for more information

$ docker run --rm ghcr.io/meta-pytorch/openenv-base:sha-562b545 python -m uvicorn --version
Running uvicorn 0.38.0 with CPython 3.11.14 on Linux

looks like it could be from #160, which copies over the libraries from a separate builder container without the launcher script in /usr/local/bin.

some examples and the envs/README.md use uvicorn as a command
