- Enhanced `useNodesInteractions` to better manage group node handlers and connections, ensuring accurate identification of leaf nodes and their branches.
- Updated logic to create handlers based on node connections, differentiating between internal and external connections.
- Refined initial node setup to include target branches for group nodes, improving the overall interaction model for grouped elements.
- Introduced GroupDefault node with metadata and default values for group nodes.
- Enhanced useNodeMetaData hook to handle group node author and description using translations.
- Added translations for group node functionality in English, Japanese, Simplified Chinese, and Traditional Chinese.
- Added headNodeIds and leafNodeIds to GroupNodeData to track nodes that receive input and send output outside the group.
- Updated useNodesInteractions hook to include headNodeIds in the group node data.
- Modified isValidConnection logic in useWorkflow to validate connections based on leaf node types for group nodes.
- Enhanced preprocessNodesAndEdges to rebuild temporary edges for group nodes, connecting them to external nodes for visual representation.
