Johann0601/buffd ? reverse-engineered prompt

Build me a Windows desktop app called buffd that acts as a single place for all my PC games, so I can see my library, launch games, track playtime, read news, and keep things organized without jumping between different launchers.

I want it to pull in games from Steam, Epic, and the other big launchers where possible, show installed and owned games, let me search and sort everything, and group games into my own collections like with friends or for relaxing. It should also track what I am playing automatically, show stats like total playtime and a heatmap, give me a news feed for installed games, and include handy extras like screenshots, store deals, wishlist support, friends, Minecraft tools, Spotify control, system and driver info, and simple update checks. Keep all data local on the PC, with a clean modern interface, and make sure the app can update itself from GitHub releases. If you need to look up current docs online, feel free to do that.
