Refactored ResizeGizmo into modular structure:
- ResizeGizmo.ts: Main implementation with Virtual Stick scaling
- enums.ts: HandleType and HandleState enums
- types.ts: TypeScript interfaces
- index.ts: Barrel exports
Implemented Virtual Stick scaling approach:
- Fixed-length virtual stick extends from controller forward
- Scaling based on distance ratio in mesh local space
- World-to-local coordinate transforms for proper rotation handling
- Smooth continuous scaling during drag (no rounding)
- Snap to 0.1 increments on grip release
- Face handles: round only scaled axis
- Corner handles: round uniformly on all axes
Fixed scaling oscillation issues:
- Freeze handle position updates during active scaling
- Prevents feedback loop between scaling and handle positioning
- Use absoluteRotationQuaternion for proper handle rotation
Added WebXRDefaultExperience parameter to constructor for proper controller integration with manual ray casting in world space.
Added test shortcuts:
- Ctrl+Shift+T: Create test entities (sphere and box)
- Ctrl+Shift+X: Clear all entities
Wired Close button to dispose active ResizeGizmo.
