X-zant/Repak-X ? reverse-engineered prompt

Build me a desktop app for Marvel Rivals modding that works on Windows and Linux. I want it to let people drag and drop mods in, install them from folders, paks, and archives, and then organize everything in a simple library so it is easy to search, filter, and manage. It should handle multiple mods at once, show progress and logs while installing, and warn me when mods conflict so I can choose which one should win.

I also want a clear mod details panel, support for light and dark mode, quick actions like open folder and copy path, and a way to replace or update mods without starting over. If you need to check the latest docs or best practices for any library, look them up online. Make it feel polished and easy for non technical users, with a clean onboarding flow and a few helpful utility tools built in.
