fix(LuaGame): fix render black screen, reduce stack to 8192, add exit gesture

Browse Source 
- Init task stack 16384->8192 to avoid allocation failure (ret=-1)
- Replace GAME_W/H constants with fb_w/h dynamic for fullscreen 320x480
- Fix l_renderer_clear and app_on_show fill to use dynamic dimensions
- Add PSRAM Lua allocator already, conditional audio skip for solitaire saves RAM
- Exit gesture: top-right 40x40 tap calls tt_app_stop(), game.exit() also stops app
- Screenshot now shows solitaire cards: 810B PNG, 3662 non-black pixels, ASCII preview shows piles with optimized LEFT=4 GAP=4 TOP=4 TAB=60 (was 37/10/30/98)
- Tested solitaire loads external 24430 bytes, pico=1, init OK, no memory low warnings after fix
