TECHBITFORGE-office/halo ? reverse-engineered prompt

Build me a simple shell based project that starts cleanly from a container or server, with a reliable start script and an entrypoint script that handle setup, environment variables, and launching the main process.

I want it to be easy to run, easy to debug, and safe if something is missing, like required config or a command not being available. If there are any best practice details I should follow for current shell and container docs, look them up online.

Make sure the scripts are polished, readable, and ready to use without extra manual steps.
