Crease - Geometry Nodes Modifier

With the addition of new geometry nodes-based modifiers included in Blender 5.0, creasing workflows could greatly benefit from this proceduralism.

A common need when working with simple geometries is to crease sharp (high angle) edges before subdividing. This could easily be done with existing nodes. Here's a simple version with controls for crease amount, angle threshold, and convex-only edge toggle.

Because it adds to the existing crease attribute, this allows for manually setting creases along with the modifier and for layering multiple Crease modifiers as mentioned in previous proposals.

This could easily be expanded to include other controls:

• Vertex creasing
• Separate convex and concave crease value
• Toggle for retaining existing creases instead of adding/overwriting

I already have this in my startup file and it'd be great for it to be included for all users!
