- Loft{profiles} op (append-only); executor resolves each profile to curve sets
all-or-nothing; backend loft() -> brep::loft on XY plane; facade solids().loft.
- entity_to_profile_curves: convert LwVertex.bulge to geom2d::Curve::Arc via
bulge_arc_segment (theta = 4*atan(bulge)), so bulged polyline profiles sweep
correctly instead of erroring Unsupported.
- spec loft; api_reference + binding_schema regenerated; mocks + baseline.
- Tests: loft_two_profiles_produces_solid, bulge_arc_polyline_profile_converts_to_arc
(semicircle radius=5 for bulge=1) -> 612 host lib + 3 consistency green.
