toprak1224/Toprak-Steam-Cracker ? reverse-engineered prompt

Build me a Windows desktop app that helps me manage Steam game manifest and LUA files in one place.

I want a simple, clean interface where I can see my installed games, pick one from a list, and then view or edit the related manifest and LUA settings without digging through folders by hand. It should remember my app settings locally, keep a small database of installed games, and make it easy to search, refresh, and save changes. If something needs to be downloaded or updated from online sources, handle that in the background so the app still feels fast.

Please make the UI feel polished and modern, with a dark theme if that fits. It should open quickly, work well on Windows, and be easy for a normal user to understand. If you need current docs or details for any webview or desktop UI behavior, look them up online and use the latest guidance.
