Snake: the snake was initialized with its head at the left end while
moving right, so the first gravity step walked the head into its own
body and the game started at Game Over. Initialize the head at the
right end (cx) so the initial direction is valid.
Tetris: enlarge the playfield cell (10 -> 12px) so pieces are not too
small, and slow gravity (800ms base, gentler per-level ramp, 250ms
floor) so pieces do not fall too fast.
Both: brighten the secondary/dim text colour (0x0a3a0a -> 0x2f9f2f)
so score/label/menu text is actually legible on the black background.
Also wire the Games section into the real main menu: the system menu
is hardcoded in the dwm-plugin dmenu (src/sxmo-dmenu/dmenu.c), not in
sxmo_appmenu.sh, so add a 'games' builtin menu that loads
sxmo_hook_games.sh and a Games entry after Apps in the sys menu, plus
scripts/build-dmenu.sh to cross-compile dmenu.so.
Add two standalone X11 games (not DWM plugins) for the Nokia 8110 keypad:
- src/games/snake.cpp: Nokia Snake II-style game, 240x296, built-in 5x7 font
- src/games/tetris.cpp: Tetris with next-piece preview, levels, line clears
Both float as dialog windows in dwm, use a self-contained bitmap font (no
font-file dependency), and are controlled via the numeric keypad (2/4/6/8
directions, 5 action) with arrow-key fallbacks.
- scripts/build-games.sh: Docker armv7 cross-compile (mirrors build-sxmo-x11.sh)
- overlay/rootfs/usr/share/sxmo/default_hooks/sxmo_hook_games.sh: Games menu hook
- overlay/rootfs/usr/bin/sxmo_appmenu.sh: add 'Games' entry after 'Apps' and a
games submenu case
Binaries committed to prebuilt/games and overlay/rootfs/usr/bin per repo
convention. Deployed and verified on the live device (window maps, dwm focuses
it, keypad input reaches the game).
