jonas-med-ett-s/idle_master_extended — reverse-engineered prompt

Build me a Windows desktop app like Idle Master Extended for Steam trading cards. I want something simple where I open it while Steam is already running and logged in, and it automatically checks which games in my library still have card drops left. Then it should pretend I am in game for those titles one by one so the cards can drop, keep checking progress, check more often when a game is almost done, switch to the next game when a title has no drops left, and close or show that it is finished when there is nothing left to farm.

Please make it feel easy to use for a normal person, with a clear interface that shows what game is currently being idled, how many drops seem to remain, and basic status or troubleshooting messages. It should match the general behavior of the original project and work on modern Windows. If anything is unclear, look up the old wiki or current Steam related docs online and fill in the gaps.
