Detailed Description

The RearrangeManager class is used to implement drag-and-drop and reordering functionality for thumbnails. This class now uses a strategy pattern to separate native drag events implementation from pointer-based implementation.

• For browsers that support drag events: uses NativeDragStrategy (based on HTML5 drag events)
• For browsers that don't support drag events well: uses PointerDragStrategy (based on pointer events + custom shadow element)

This design makes the code more maintainable and testable by separating the two different drag implementations.
