mamiiblt/instafel ? reverse-engineered prompt

Build me a modular open source app suite for customizing the latest Instagram Alpha APKs. I want one main app that gives users a clean interface with menus, dialogs, and settings for Instafel features, plus a patching system that can inject those features into Instagram APKs. It should also include a core layer for the patch logic, an updater so users can stay on the latest version without thinking about it, and a simple website with guides, resources, and helpful documentation. If needed, include a way to fetch the newest Instagram Alpha APKs directly from Google Play. Make the experience feel polished and easy to use, even for someone who is not very technical. Keep it organized so the different parts work together cleanly, and if you need current docs or implementation details, look them up online and iterate as needed.
