Parallel animation updates, thread-safe collision, M2 pop-in fix, shadow stabilization

Browse source 
- Overlap M2 and character animation updates via std::async (~2-5ms saved)
- Thread-local collision scratch buffers for concurrent floor queries
- Parallel terrain/WMO/M2 floor queries in camera controller
- Seed new M2 instance bones from existing siblings to eliminate pop-in flash
- Fix shadow flicker: snap center along stable light axes instead of in view space
- Increase shadow distance default to 300 units (slider max 500)
