NightwindDev/rootless-patcher — reverse-engineered prompt

Build me a small command line tool called rootless patcher that takes the path to an iOS .deb package and converts a rootful jailbreak package into a rootless one. I want it to work from Terminal on iOS and macOS, and on iOS it should also be usable as a Filza script for people on a jailbroken device. The main goal is a simple command like rootless patcher <path/to/deb> that patches the package without relying on Xina style symlinks.

Please make it feel like a real installable utility, with packages people can install on rootless iOS, rootful iOS, and macOS. If there is already a writeup in the repo, follow that approach and keep the implementation aligned with it. I also want the project set up so someone can build it manually with Theos and get the expected installable packages out of the box. Keep the usage straightforward, handle common errors cleanly, and add a short README with install and usage steps. Look up current docs if you need to.
