feat(pocketdungeon): intro GOAL+CONTROLS left icons right + 2x2 tutorial levels

- Intro redesign QVGA: left scrollable column 2 cards GOAL+CONTROLS only,
  right 44px rail small icons Play 38 accent + Exit 30 muted (fixes cramped)
- Tutorial by play: floor0 TUTORIAL_ROWS=2 player+stairs, floor1 bat+gold+stairs,
  real game from floor2 infinite with displayFloor mapping
- Model: renderRows, isTutorial(), tutorialId(), clearAllTiles(), generateTutorialFloor
- Renderer: respects renderRows HIDDEN, board height 2 rows centered, TUT messages
- Game: reset tutorials=true, skip moveMonsters in tutorial, bests only real floors
- Keep audio-stream migration: SDK 0.8.0-dev IDF5.5, CMake GLOB SfxEngine, SfxEngine audio-stream
- No unexported LVGL: no max_width/scrollbar_mode -> 0 missing symbols
