feat(v12): generative surfaces (Sweep/Loft/Net) + curve tools + surface analysis

M1 — Generative Surfaces: - sweep_surface: Explicit/Spine/TwoGuides modes - loft_surface: multi-section interpolation + guide + tangent constraints - net_surface: bidirectional curve grid → NURBS M3 — Curve Tools + Analysis: - curve_tools: project_curve, parallel_curve, connect_curve(G1-G3), helix, isoparametric - surface_analysis: inflection_lines, checker_mapping, surface_checker_report (A/B/C/D) - 14/14 tests passed Fixed: constraint_solver.h duplicate declaration, fea_mesh.h comment syntax Pending: M2 surface editing (retrying)
