NiiV3AU/YMU ? reverse-engineered prompt

Build me a clean desktop launcher for YimMenu that feels modern and easy to use.

I want a Python app with a PySide6 interface, light and dark themes, that lets me download and manage the latest DLL, check its SHA 256 hash before using it, and then launch GTA V and move into the inject flow from inside the app. It should also have a simple place to manage Lua scripts, remember my choices, and show clear status messages if something goes wrong. Please make it work for both GTA V Legacy and Enhanced, and include a settings area for game path, custom DLL use, and other basic preferences. If there are translations available, wire those in too.

Keep it polished and fast, with a friendly layout that matches a real launcher people would actually use. If you need current docs for anything, look them up online first.
