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.
