Pull request overview
This PR implements comprehensive performance optimizations and new features for the Object UI Designer. The primary goal is to enhance the designer's capabilities through React performance improvements and professional UX features.
Changes:
- Performance optimizations using React.memo, useCallback, and useMemo across all major components (60% reduction in re-renders)
- New Component Tree View for hierarchical navigation with expand/collapse, visibility toggles, and synchronized selection
- New Context Menu with right-click actions (Copy, Cut, Paste, Duplicate, Delete) and keyboard shortcuts

The isSelected prop checks if the child's ID equals selectedNodeId, but this doesn't account for nested children deeper in the tree. When a deeply nested node is selected, its parent nodes won't properly highlight the selection path. Consider checking if selectedNodeId exists anywhere in the child's subtree, not just at the immediate child level.

Fixed in commit c4410b2. Added hasSelectedDescendant check that recursively searches through the node's subtree to determine if any descendant is selected. Parent nodes now show a lighter blue border (border-blue-300) when they contain the selected node, making the selection path visible throughout the tree hierarchy.

The comment 'Don't show context menu for root' explains the intent, but the logic prevents the context menu for the root node specifically by comparing against schema.id. Consider extracting this into a named constant like ALLOW_ROOT_CONTEXT_MENU or a helper function to make the business logic more explicit and maintainable.

Fixed in commit c4410b2. Extracted the logic to a named constant ALLOW_ROOT_CONTEXT_MENU = false at the top of the file. The business logic is now more explicit with a clear isRoot check and the constant makes it easy to change this behavior if needed in the future.
