Refactored exit XR button creation from rigplatform to toolbox for better organization and UI cohesion.
- Add setXR() methods to DiagramManager, DiagramMenuManager, and Toolbox to pass WebXRDefaultExperience after initialization
- Create setupXRButton() in Toolbox class that creates button when entering XR
- Position button at bottom-right of toolbox (x: 0.5, y: -0.35, z: 0)
- Use Y-axis rotation (Math.PI) for correct orientation within toolbox coordinate system
- Scale button to 0.2 for appropriate size
- Remove button creation code from rigplatform
Exit button now moves with toolbox and is logically grouped with other UI elements.
