BuSung-dev/Root-My-Galaxy-Payloads ? reverse-engineered prompt

Build me the device specific side of Root My Galaxy for a few Samsung models I own, with the firmware profiles, offsets, exploit payload, app bootstrap helper, and the KernelSU build artifacts all wired together so the right files get produced for each target.

I want to be able to run one make command with a target and get the matching payloads in a build folder, plus a release build for the app payload when needed. Please make it easy to support the listed Galaxy S series and A series models, and keep the support feed and compatibility data in sync with the current commit so the app can fetch the right artifacts.

If anything is unclear, look up the current docs online and follow the existing repository notes. Keep it focused on the native payloads and artifacts only, since the Android app source is not part of this repo.
