Actual UV Seam Overlay

It would be very useful to have an option to show actual UV seams in overlays.

Blender currently shows marked seam edges in the 3D Viewport, but these do not always match real UV seams. In the UV Editor, there is currently no seam overlay at all.

The overlay could work in both the 3D Viewport and the UV Editor, showing actual UV seams based on the active UV map.

This would make UV debugging clearer, especially for imported assets and meshes edited with Correct Face Attributes enabled. These splits are easy to miss when they are small, local, or hard to notice in a dense UV layout.
