YGame

A small, polished Tic-Tac-Toe game written in Rust with the egui GUI
toolkit. Pick a difficulty before each round:

* Easy – the computer plays random moves.
* Medium – the computer wins when it can, blocks your wins, otherwise

          plays sensibly.

* Hard – a full minimax search; the computer never loses.

The match scoreboard (wins / losses / draws) is kept on screen so you can
track how you're doing against each difficulty.
