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).
Text-input dialogs (Wi-Fi SSID/Passphrase, search queries, config
prompts, etc.) invoke dmenu with -p but never -t, so the XIM/fcitx
routing that was gated solely by use_text_input was never enabled and
fcitx never activated on dmenu input; on the numeric keypad only raw
digits could be entered, making the dialogs non-functional.
Decouple the fcitx/IME routing from the -t flag via a new engage_ime
flag (default on) while keeping use_text_input for its output/selection
semantics, and skip routing Enter to fcitx when a menu list is present
so menu selection is never stolen by the T9 commit. XFilterEvent already
returns False when fcitx is toggled off via the mode switcher, so the
dialogs now respect the Fcitx mode switcher automatically.
