adding an option to smooth or reset the lengths of Bézier curve handles for consistent handle scaling.

These curves are automatically generated by the Curve Brush, but I couldn’t find any option to smooth or reset the lengths of Bézier curve handles. Currently, Blender only offers tools to change the handle type (e.g., Auto, Aligned, Free) or smooth the positions of the curve points—but there’s no built-in way to equalize or reset the handle lengths themselves. A dedicated function to reset or smooth Bézier handle lengths (for example, making both sides of a handle equal in length while preserving direction) would be extremely helpful for cleaning up auto-generated curves.
