termux/proot-distro ? reverse-engineered prompt

Build me a command line tool for Termux and regular Linux that lets me manage rootless Linux containers with proot, kind of like a lightweight container manager without needing root or Docker. I want to be able to search for images, install a container from Docker Hub or another OCI registry, start a shell inside it, run a one off command, list containers, see active sessions, stop them, rename them, remove them, and back up or restore them. It should also support building an OCI image from a Dockerfile locally, installing that image, and pushing it to a registry if needed. Make it feel polished and practical, with clear help text, sensible defaults, and good error messages, especially for missing proot or unsupported setups. If it makes sense, add a short alias for the main command too. Look up current docs online if you need to.
