feat(LuaGame): Lua interpreter game engine with audio, 17 FPS, 4.5x ball speed

- Embed Lua 5.4.7 source to avoid missing symbols (clearerr, clock, getenv, etc) - Provide local stubs for missing libc and avoid unexported LVGL cache APIs - Fix float handling in sys.* bindings (checknumber vs checkinteger) - Move Lua init and game loop to dedicated 16K FreeRTOS task to avoid GUI 4K stack overflow - Implement sys API: clear, print (8x8 bitmap font direct FB), rect, circle, line, touch, sfx, tone - Audio via SfxEngine (SfxId mapping, playNote for tone) - Ball speed 2 -> 4.5, FPS counter (~17 FPS after direct FB text optimization) - Supports loading from /sdcard/lua/breakout.lua and embedded fallback - Verified symbols: 0 missing, builds esp32s3, installs on 192.168.68.107
