説明

Like with BoundingBox and few other shapes, it would be good to have a rectangle, that is much simpler shape than box, and would be useful in many cases.

It would have position, rotation and size (not halfExtents please). And would have functionality to check if it intersects with ray or other shapes.

調査方針
Review the existing BoundingBox implementation in the PlayCanvas engine to understand the shape interface. Implement a Rectangle class with position, rotation, and size properties, and add intersection methods for ray and other shapes. Ensure rotation is handled properly. Check the issue comments for any additional requirements or previous attempts.
