PolyCurve#

Ordered chain of 3D curve segments ({ segments: Curve[] }). Curve-entity geometry. Arc-length domain [0,1]; add auto-reverses for G0 join (tol 1e-7). Factories: polyline/line/fromPoints/fromNurbs/fromCurveJson. Kind predicates (isLine/isArc/isEllipse/isNurbs/isPolyline/isSingleSegment) are pure segment-tag queries — type: "segment" window arms never match pure kinds. Not Wire (no branching).
