Performance optimizations: sound caching, renderer culling, entity and lighting improvements

Browse Source 
- Sound engine: cache filesystem probe results to avoid repeated file existence checks; add MA_SOUND_FLAG_DECODE for pre-decoded playback
- Level renderer: column-level frustum culling, compact visible chunk lists to skip empty iteration, lightweight second-pass render path, early-out for non-dirty chunks, scaled recheck period at high render distances
- Entity: cache shared_from_this() to reduce reference counting overhead in move() and checkInsideTiles()
- Level: skip checkLight() when tile light properties unchanged; enable entity locking on all platforms (not just Vita)
- LevelChunk: only rescan min height when the minimum column changes; defer lightGap processing
- LivingEntity: use raw pointer cast instead of dynamic_pointer_cast; cache friction tile lookup
- ServerPlayerGameMode: return whether block was destroyed to avoid redundant tile update packets
