Add IGES v5.3 export for B-Rep models with: - Entity mapping: Point(116), Line(110), Circular Arc(100), B-Spline Curve(126), Plane(108), B-Spline Surface(128), Vertex(502), Edge(504), Loop(508), Face(510), Shell(514), Manifold Solid B-Rep(186) - Auto-detection of circular arcs (degree-2 NURBS with isosceles control triangle) and planes (1x1 degree surfaces) - Fixed 80-column IGES format with S/G/D/P/T sections - Header-only format_utils.h for IGES/STEP number formatting New files: - include/vde/foundation/format_utils.h - include/vde/brep/iges_export.h - src/brep/iges_export.cpp - tests/brep/test_iges_export.cpp
