games: responsive game loop with non-blocking input polling

Browse Source

Replaced the blocking select()-based main loop with a proper game loop:
- Process ALL pending X11 input (XPending) before every frame — no more
  missed keypresses from select() blocking for up to a full frame
- Render every frame at 30 fps (FRAME_MS = 33 ms) consistently
- Frame pacing uses select() with a timeout that wakes immediately on
  input, so keypresses are processed within milliseconds
- Game logic (snake steps, tetris gravity) still runs at its own rate via
  nextTick, decoupled from render rate

This eliminates input lag and missed keypresses in both Snake and Tetris.
