feat: add collapsible/expandable zones for canvas decluttering

- Add collapsed state to NodeData.custom_colors (type=groupRect only) - Implement toggleNodeCollapsed action in canvasStore (Zustand) - Extend GroupRectNode UI with smooth chevron toggle button - Rotating chevron icon (↓ → when collapsed) - Shows '+N' badge when zone is hidden - Reduces zone opacity to 0.6 when collapsed - All transitions target 60 FPS (ease-out 200ms) - Filter child nodes/edges in CanvasContainer based on parent collapse state - Breadth-first traversal handles multi-level nesting - Connecting edges to hidden nodes are automatically hidden - Add comprehensive test coverage - Store: toggleNodeCollapsed state mutation, unsaved flag - Component: chevron rendering, click handlers, opacity transitions - Persist collapsed state via YAML serialization (part of custom_colors) Benefits: - Declutter large Zigbee meshes, multi-building networks - Preserve layout structure without deleting nodes - Smooth 60 FPS transitions for UX polish CONTRIBUTING.md compliance: - Strict TypeScript types, no 'any' - Zustand store pattern, no prop drilling - Tests for store logic and component behavior - Frontend linting requirements met Co-authored-by: CyberClaw <noreply@openclaw.ai>
