Model management:
- Add list_models, get_current_model, set_model tools

- Model selection persists for session duration
Directional placement improvements:
- Compute ground-projected forward/right vectors from camera
- Accounts for camera being parented to moving platform
- "Forward" means forward on ground plane, ignoring vertical look angle
- Pre-calculate example positions for left/right/forward/back
- Update system prompt to use get_camera_position for relative directions

- Add get_camera_position tool for positioning entities relative to user view
- Fix color change causing entities to disappear (dispose mesh before rebuild)
- Fix connections being lost when modifying entities (defer disposal, let
scene observer re-find meshes after they're recreated with same ID)
- Add position and color setters to DiagramObject for real-time updates
- Add debug logging to diagramAI and claude.js for troubleshooting

Implement session management to maintain conversation history and entity
context across page refreshes. Sessions are stored in-memory and include:
- Conversation history (stored server-side, restored on reconnect)
- Entity snapshots synced before each message for LLM context
- Auto-injection of diagram state into Claude's system prompt
Key changes:
- Add session store service with create/resume/sync/clear operations
- Add session API endpoints (/api/session/*)
- Update Claude API to inject entity context and manage history
- Update ChatPanel to initialize sessions and sync entities
- Add debug endpoint for inspecting session state

Label Positioning Fixes:
- Fix labels accounting for mesh scaling using maximumWorld coordinates
- Labels now properly positioned on scaled objects (spheres, boxes, etc.)
- Restore world→local coordinate transformation in updateLabelPosition
Billboard Mode Implementation:
- Add configurable label rendering modes: fixed, billboard, dynamic, distance-based
- Implement billboard mode (labels always face camera using BILLBOARDMODE_Y)
- Add label rendering mode to AppConfig with default 'billboard'
- Add UI selector in ConfigModal for label rendering mode
- Observable pattern updates all existing labels when mode changes
XR Entry Positioning Fix:
- Synchronize desktop camera position to platform before entering XR
- Transfer camera world position and rotation to prevent scene shift
- Reset physics velocity on XR entry to prevent drift
- Add debug logging for position synchronization
Config System Architecture Fix:
- Create singleton appConfigInstance to ensure single source of truth
- Update DiagramObject to use singleton instead of creating instances
- Update DiagramManager to use singleton
- Fix ConfigModal to update AppConfig directly (was only updating legacy config)
- ConfigModal now triggers Observable notifications via appConfigInstance setters
- Maintain legacy config for backward compatibility
- Fixes issue where label rendering mode changes didn't take effect
Files Modified:
- src/diagram/diagramObject.ts - Label positioning, billboard mode, singleton config
- src/diagram/diagramManager.ts - Use singleton config
- src/util/appConfig.ts - Add labelRenderingMode, export singleton
- src/util/appConfigType.ts - Add LabelRenderingMode type
- src/react/pages/configModal.tsx - Update AppConfig directly, add label mode UI
- src/util/functions/groundMeshObserver.ts - Add camera position sync on XR entry
- public/api/user/features - Update test config
- package.json - Version bump

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.

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.
