Function intersectCurves2d

intersectCurves2d(
    c1: Curve2DHandle,
    c2: Curve2DHandle,
    tolerance?: number,
): Result<{ points: Point2D[]; segments: Curve2DHandle[] }>
Find intersection points and overlap segments between two 2D curves.

Returned segments are individually disposable — callers must dispose each element when done.
Parameters
- c1: Curve2DHandle
- c2: Curve2DHandle
- tolerance: number = 1e-7
  Intersection tolerance (default: 1e-7).
Returns Result<{ points: Point2D[]; segments: Curve2DHandle[] }>
