feat: add 6 lua games for basic1 console
- Pong: 2-player paddle and ball game with spin mechanics - Flappy Bird: gravity physics, obstacle avoidance - Breakout: paddle control, brick grid, collision detection - Simon Says: sequence memory, animation timing - Memory Match: pair matching, flip animations, grid layout - Tetris: falling blocks, grid system, line clearing - Asteroids: vector math, rotation, projectiles, enemy spawning All games follow API conventions with state machines, touch input, frame-based animation, and persistent game.vars state management.
