Implements visual grouping of actors with context menu operations,
resizable containers, and complete history tracking integration.
Features:
- Create groups from multiple selected actors via context menu
- Groups visualized as resizable containers with child nodes
- Ungroup actors (non-destructive) or delete group with actors
- Right-click context menu with group-specific operations
- Dedicated GroupEditorPanel for group properties
- Smart minimum size constraint based on child node positions
- Full undo/redo support for group operations and resizes
Technical Implementation:
- GroupNode component with React Flow NodeResizer integration
- Atomic createGroupWithActors operation for consistent history
- Parent-child relationship using React Flow v11 parentId pattern
- Groups stored separately from actors in graphStore
- Fixed history tracking to sync graphStore before snapshots
- Resize tracking to prevent state sync loops during interaction
- Dynamic minimum dimensions to keep children inside bounds
- Sanitization of orphaned parentId references on state load
History Fixes:
- pushToHistory now syncs timeline with graphStore before snapshot
- Prevents missing groups/nodes in history states
- Ensures undo/redo correctly restores all graph elements
- Atomic state updates to avoid React Flow processing stale state
Storage & Persistence:
- Groups saved in timeline states and document structure
- Safe JSON serialization to prevent prototype pollution
- Cleanup utilities for removing __proto__ from localStorage
