This commit adds a Dockerfile and wrapper script that allows a chantool image to be used as an Umbrel app for easy use by non-technical users. The "app" only spins up a background container that can be executed into and run CLI commands manually. The entrypoint and bash wrapper scripts are only there to give guidance and improve UX.
