Self contained just docker idea (down the road idea)

How to make a docker that doesn't need the source code dir checked out?

• Make the container run on its own, we already do that by adding /vsi, Justfile, env file, etc...
• Make it detect that it's running rouge
• It can print out a helpful message like "Oh, I see you are running the container standalong, to configure just run docker run -e DOCKER_UID=id -u-vpwd:/setup docker_image_name some_command_here. Now its easy to remember what needs to be run for the advcanced setup
• Now when it runs some_command_here, it will write out the docker-compose files, and other minimalist files needed for the more advanced setup, extreme would be copying out vsi_common, etc. But that's an option

Start by reviewing the existing standalone container setup, including /vsi, the Justfile, and the env file. Define how the container detects standalone execution, what helpful message it should print, and which docker-compose and other minimalist files should be generated. Done means the full standalone workflow and advanced setup behavior are specified and verified.
