Schema v2.0: outer_boundary is now a list of typed segments:
- {type: 'line', start: [x,y], end: [x,y]}
- {type: 'arc', start: [x,y], end: [x,y], center: [x,y], radius: R, clockwise: bool}
Extract: detect arcs via UF Eval.IsArc/AskArc, output exact geometry.
Import: create NX sketch arcs (3-point) for arc segments, backward-compatible with v1.0 polylines.
