Replace emissive-only rendering with diffuse + lightmap system to achieve realistic lighting appearance without dynamic light overhead.
- Create LightmapGenerator class with canvas-based radial gradient generation
- Generate one lightmap per color (16 total) using top-left directional light simulation
- Cache lightmaps in static Map for reuse across all instances
- Preload all lightmaps at toolbox initialization for instant availability
- Update buildColor() to use diffuseColor + lightmapTexture instead of emissiveColor
- Update buildMissingMaterial() to use lightmap-based rendering
- Enable lighting calculations (disableLighting = false) to apply lightmaps
Lightmap details:
- 512x512 resolution RGBA textures
- Radial gradient: center (color × 1.5), mid (base color), edge (color × 0.3)
- Simulates top-left key light with smooth falloff
- Total memory: ~16 MB for all lightmaps
- Zero per-frame performance cost

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.

Changed EdgesRenderer to work on individual instances instead of source mesh to prevent all instances from highlighting when one is hovered.
- Remove edgesShareWithInstances flag (was causing all instances to highlight)
- Enable/disable edges directly on hovered instance
- Adjust edge width to 0.2 and color to pure white for cleaner appearance
- Remove metadata tracking in favor of checking edgesRenderer directly
This ensures only the specific hovered entity shows visual feedback while maintaining haptic feedback for all interactions.

- Use camera.getDirection() instead of manual Euler angle calculation to properly account for camera transform hierarchy
- Negate forward offsets to position objects in -Z direction (user faces -Z by design)
- Replace expensive HighlightLayer hover effect with lightweight EdgesRenderer (20-50x faster)
- Add comprehensive debug logging for position calculations
The camera has a parent transform with 180° Y rotation, causing the user to face -Z in world space. Components now correctly position in front of the user when entering XR.

Performance improvements:
- Added Vector3 position caching for connection endpoints
- Only update connections when meshes actually move (>0.001 units)
- Use DistanceSquared for efficient movement detection
- Replace inefficient vector length comparison
Impact:
- Static connections: 0 raycasts/second (was ~20/sec per connection)
- With 10 connections: 90-99% reduction in raycast operations
- Eliminates unnecessary curve geometry recreation
Implementation:
- Added _lastFromPosition and _lastToPosition caching
- Created hasConnectionMoved() method with tolerance threshold
- Reset cache on mesh removal and initial setup
- Clean up cache in disposal method
This dramatically reduces CPU usage in VR with multiple connections.

Removed console.log() from connectionPreview render observer that was
executing every frame during connection dragging. This eliminates I/O
blocking and stringification overhead in the critical VR render path.
Performance: Quick win for VR framerate improvement.

Lighting changes:
- Disabled HemisphericLight in customEnvironment
- Changed all materials from diffuse to emissive colors
- Added disableLighting=true to all StandardMaterials
- Updated toolbox colors, diagram entities, and spinner
Bug fix:
- Fixed "Cannot read properties of undefined (reading 'pickedMesh')" error
- Added defensive check in DiagramObject.updateConnection()
- Now validates hit array has at least 2 elements before accessing
Materials now render at full brightness with unlit/flat shading.

When entering immersive mode, toolbox and input text view now position
themselves relative to the user's initial camera position:
- Toolbox: 0.5m ahead, 0.5m below, 0.2m to the left
- Input text view: 0.5m ahead, 0.5m below (centered)
Uses camera world Y position to ensure vertical offset is consistent
regardless of head pitch/tilt when entering XR.
Also added CLAUDE.md documentation for the codebase.
