rachitjain2/VeilOS ? reverse-engineered prompt

Build me a disposable Linux live system called VEILOS that boots from a USB or in a VM and runs everything in memory by default, so nothing touches the host drive unless I explicitly save it. I want a simple launcher experience with a private browser, a developer workspace for Node, Python, Git, and basic build tools, and a locked down app testing mode that has no network access. Also include a secure vault for saved files, plus a privacy screen that shows what is enforced and what is only partially supported.

Make it build into a bootable ISO from the scripts in the repo, and include the test flow so I can run the checks and demo it easily. If anything depends on current Debian or live build docs, look up the latest info online and use that. Keep the whole thing honest and practical, with clear limits instead of pretending to do security it cannot really do.
