topjohnwu/Magisk — reverse-engineered prompt

I want you to turn this repo into a working Android root and customization tool, basically a full Magisk style build I can compile and use. It should support Android 6 and newer, give apps root access, let users install and manage modules that change the system without directly rewriting read only partitions, and include the boot image patching and repacking flow needed for installation. It should also include the app side for managing install status, root permissions, modules, and logs, plus the runtime hook support that runs code inside app processes.

Please wire up whatever app and native parts are needed so the project actually builds cleanly from source and the main features are usable. I also want debug builds and logging set up properly, since that is important for troubleshooting. Keep it aligned with the existing docs and release flow in this repo, and if you need details, look up the current install and build docs online.
