FlexingCodes/ChessCheat ? reverse-engineered prompt

Build me a simple Python chess helper that uses Stockfish to analyze positions and suggest the best move.

I want it to be able to look at the screen, find a chessboard, and keep tracking it if the board moves around, even if those parts are rough for now. It should show the analysis in a small, easy to use interface and let me point it at the Stockfish executable path if needed.

Please make it work as a local tool I can run from the source, and keep the code easy to read so I can learn from it and tweak it later. If you need to check the current Stockfish setup or any library details online, go ahead and look them up. Also make sure it handles missing Stockfish clearly, since that seems important for this project.
