Phase 1 & 2: Handle positioning and wireframe improvements
- Move handles 5% outward from bounding box (was inward)
- Rename boundingBoxPadding → handleOffset for clarity
- Add wireframePadding (3% breathing room around mesh)
Hover boundary detection (prevent loss in whitespace):
- Add isPointerInsideHandleBoundary() with ray-AABB intersection
- Use local space transformation for accurate OBB handling
- Keep HOVER_MESH state when pointer in handle boundary
- Fix: Trust ResizeGizmo state instead of recreating with fake rays
Prevent main scene mesh grab during handle interaction:
- Add ResizeGizmo state check in pointer observable
- Add defense-in-depth guard in grab() method
- Prevents controller from grabbing diagram mesh when hovering handle
- Two-level protection against race conditions
