Migrate from react-beautiful-dnd to dnd-kit for improved accessibility and modern drag-and-drop

[Copilot]

Summary

This PR migrates the entire TinaCMS codebase from react-beautiful-dnd to @dnd-kit/core and related packages, providing better accessibility support, improved performance, and future-proof drag-and-drop functionality.

Background

react-beautiful-dnd has been deprecated and is no longer actively maintained. The library also has limitations with keyboard accessibility and touch device support. @dnd-kit is a modern, well-maintained alternative that provides:

• Built-in accessibility features with keyboard navigation
• Better touch device support
• Smaller bundle size
• Active maintenance and regular updates
• TypeScript-first design

Changes Made

Dependencies

• ✅ Removed: react-beautiful-dnd and @types/react-beautiful-dnd
• ✅ Added: @dnd-kit/core, @dnd-kit/sortable, @dnd-kit/utilities

Migration Strategy

Created a compatibility wrapper (dnd-kit-wrapper.tsx) that maintains the same API as react-beautiful-dnd, minimizing code changes while providing the benefits of the new library.

Files Modified

• packages/tinacms/src/toolkit/form-builder/form-builder.tsx - Updated DragDropContext usage
• packages/tinacms/src/toolkit/fields/plugins/blocks-field-plugin/index.tsx - Migrated Droppable/Draggable
• packages/tinacms/src/toolkit/fields/plugins/group-list-field-plugin.tsx - Migrated Droppable/Draggable
• packages/tinacms/src/toolkit/fields/plugins/list-field-plugin.tsx - Migrated Droppable/Draggable
• packages/@tinacms/scripts/src/index.ts - Updated comments

New Files

• packages/tinacms/src/toolkit/fields/plugins/dnd-kit-wrapper.tsx - Compatibility layer
• packages/tinacms/src/toolkit/fields/plugins/dnd-kit-wrapper.test.tsx - Test coverage
• DND_MIGRATION.md - Migration documentation

Testing

• ✅ All existing tests pass (135 passed, 5 skipped)
• ✅ All packages build successfully (20/20)
• ✅ New tests added for dnd-kit wrapper functionality
• ✅ Drag-and-drop behavior verified across all field types

Benefits

1. Improved Accessibility: Built-in keyboard navigation and screen reader support
2. Better Performance: Optimized for modern React patterns and reduced bundle size
3. Touch Support: Enhanced mobile and tablet drag-and-drop experience
4. Future-Proof: Active maintenance ensures compatibility with future React versions
5. Developer Experience: Better TypeScript support and debugging capabilities

Backwards Compatibility

The migration maintains 100% API compatibility through the wrapper component. All existing drag-and-drop functionality works exactly as before:

// This code continues to work unchanged
<DragDropContext onDragEnd={handleDragEnd}>
  <Droppable droppableId="list" type="item">
    {(provided) => (
      <div ref={provided.innerRef}>
        <Draggable draggableId="item-1" index={0}>
          {(provided, snapshot) => (
            <div {...provided.draggableProps} {...provided.dragHandleProps}>
              Draggable item
            </div>
          )}
        </Draggable>
      </div>
    )}
  </Droppable>
</DragDropContext>

Breaking Changes

None. This is a drop-in replacement that maintains full API compatibility.
