Subject: [PATCH] Display real-time CPS in terminal game HUD

Added real-time Clicks Per Second (CPS) tracking and display to the live game HUD in `src/main.cpp`. The CPS metric is updated continuously during gameplay and formatted to one decimal place, providing immediate tactile feedback to the player.
