feat: add final 4 games for basic1 console
- 2048: Grid merging, directional movement, score tracking, win/draw detection - Tic-Tac-Toe: Minimax AI opponent, perfect play, win detection - Lunar Lander: Gravity + thrust physics, fuel management, landing validation - Air Hockey: Refined paddle physics, puck acceleration, goal detection All games tested for state transitions, collision logic, and win conditions. Suite now complete with 10 classic games ready for SD card deployment.
