physics: capsule/cylinder/compound collider shapes

Browse Source 
- ColliderType + Capsule/Cylinder/Compound; CompoundChild list (Box/
  Sphere/Capsule, local pos/quat, non-recursive)
- CreateBody: CapsuleShape/CylinderShape (ctor param orders differ) +
  StaticCompoundShape; empty/failed compound falls back to Box
- BodyRecord caches radius/halfHeight/compound; SyncScene rebuilds on
  change (per-collider param extraction)
- Inspector: combo entries + shape params + compound child list editor
- Serialization: new fields with as<T> fallback, compound seq round-trip
