Clean up AbstractController by removing references to old ResizeGizmo implementation:
- Remove utility layer mesh filtering logic
- Remove auto-show gizmo on hover
- Remove gizmo handle click filtering
- Remove unused Ray import
- Bump version to 0.0.8-26
These changes complete the migration to the new simplified ResizeGizmo architecture.

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

Handle meshes now correctly rotate to match the target mesh's world-space
orientation instead of appearing axis-aligned.
Root Cause:
- Handle positions from HandleGeometry are calculated in world space
- Setting mesh.position treats values as local space
- This created coordinate system mismatch when rotation was also set
- Result: rotation appeared to have no effect
Solution:
- Extract rotation from mesh world matrix using quaternion decomposition
- Set rotation FIRST (before position)
- Use setAbsolutePosition() for world-space positioning
- This ensures rotation and position work correctly together
Changes:
- Import Quaternion from @babylonjs/core
- Update createHandleMeshes(): decompose world matrix, set rotation,
then use setAbsolutePosition()
- Rename updateHandlePositions() to updateHandleTransforms()
- Update updateHandleTransforms(): same rotation-then-position approach
- Add null check for _targetMesh in updateHandleTransforms()
Technical Details:
- computeWorldMatrix(true) gets complete transform including parent
- decompose() extracts pure rotation as quaternion (avoids gimbal lock)
- setAbsolutePosition() correctly handles world-space coords with rotation
- Order matters: rotation before position for correct transformation
Result:
✅ Handle box shapes visually tilt/rotate with mesh
✅ Handles remain correctly positioned on OBB
✅ Both wireframe and individual handles rotate together

- Implement comprehensive WebXR resize gizmo system with three handle types:
- Corner handles: uniform scaling (all axes)
- Edge handles: two-axis planar scaling
- Face handles: single-axis scaling
- Use "virtual stick" metaphor for intuitive scaling:
- Fixed-length projection from controller to handle intersection
- Distance-ratio based scaling from mesh pivot point
- Works naturally with controller rotation and movement
- Add world-space coordinate transformations for VR rig parenting
- Implement manual ray picking for utility layer handle detection
- Add motion controller initialization handling for grip button
- Fix color persistence bug in diagram entities:
- DiagramEntityAdapter now uses toDiagramEntity() converter
- Store color in mesh metadata for persistence
- Add dependency injection for loose coupling
- Extract DiagramEntityAdapter to integration layer:
- Move from src/gizmos/ResizeGizmo/ to src/integration/gizmo/
- Add dependency injection for mesh-to-entity converter
- Keep ResizeGizmo pure and reusable without diagram dependencies
- Add closest color matching for missing toolbox colors
- Handle size now relative to bounding box (20% of avg dimension)
