Tracking Issue: Refactor nodes to use Kurbo instead of Bezier-rs

[indierusty]

• 'Offset Path' node (Replace Bezier-rs use in the 'Offset Path' node with a Kurbo algorithm #2596, Refactor the 'Offset Path' node to use Kurbo entirely #2946)
• 'Solidify Stroke' node (Refactor the Solidify Stroke node implementation to use the Kurbo API #2608)
• 'Position on Path' and 'Tangent on Path' nodes (Refactor the 'Position on Path' and 'Tangent on Path' nodes to use the Kurbo API #2611)
• 'Sample Points' node (Refactor the 'Sample Points' node to use Kurbo instead of Bezier-rs #2629)
• 'Scatter Points' node (Refactor the 'Scatter Points' node to use Kurbo instead of Bezier-rs #2634, Fix 'Scatter Points' node artifacts #2657)
• 'Bounding Box' node (Refactor the 'Bounding Box' node to use Kurbo instead of Bezier-rs #2662)
• 'Morph' node (Refactor the 'Morph' node to use Kurbo instead of Bezier-rs #2696)
• 'Spline' node (Refactor the 'Spline' node to use Kurbo instead of Bezier-rs #2701)
• 'Bevel' node (Fix the Bevel node so it applies a consistent bevel size regardless of angle #2293)
• 'Area' node (Fix the Bevel node so it applies a consistent bevel size regardless of angle #2293)
• 'Round Corners' node (Refactor the 'Round Corners' and 'Auto-Tangents' nodes and vector node unit tests to use Kurbo #2964)
• 'Auto-Tangents' node (Refactor the 'Round Corners' and 'Auto-Tangents' nodes and vector node unit tests to use Kurbo #2964)
• 'Centroid' node (Refactor the Centroid node and Subpath struct and methods to use Kurbo, eliminating all remaining usages of Bezier-rs #3036)
