Add 14-part tutorial Python files (extracted, tested)

Tutorial scripts extracted from documentation, with fixes:
- Asset filename: kenney_roguelike.png → kenney_tinydungeon.png
- Entity keyword: pos= → grid_pos= (tile coordinates)
- Frame.size property → Frame.resize() method
- Removed sprite_color (deferred to shader support)

All 14 parts pass smoke testing (import + 2-frame run).
