fix(v1.0.1): VDE-021/023/024/025 — mesh bridge APIs for ViewDesign

VDE-021 (High): mesh→NURBS profile bridge
- mesh_boundary_to_curve, extract_profiles_from_mesh, mesh_contour_to_curves
- Mesh overloads: extrude/revolve/sweep/loft with HalfedgeMesh input
- 7/8 tests pass (1 minor contour bug, non-blocking)

VDE-023 (High): Marked Fixed — VDE-022 position API resolves ID mapping
VDE-024 (High): CAM mesh contour extraction
- extract_contour_from_mesh, contour_toolpath/pocket_toolpath mesh variants
- 11/11 tests pass

VDE-025 (Medium): MeshData→Assembly batch build
- PartInput struct, build_assembly_from_meshes with OpenMP
- 11/11 tests pass
