茂之钳 6cfd186780 feat(brep): S13-A — IGES import support
CI / Build & Test (push) Failing after 33s
Details
CI / Release Build (push) Failing after 32s
Details 
Implement IGES (Initial Graphics Exchange Specification) file reader that
converts IGES entities to B-Rep models.

Key features:
- 80-character fixed-width card image parser (S/G/D/P/T sections)
- Directory Entry parsing with all 18 DE fields per entity
- Parameter Data parsing with DE pointer tracking
- D exponent notation support (e.g., 1.5D+2 = 150)

Supported IGES entity types:
  Curve entities (→ NurbsCurve):
    Type 100 - Circular Arc (rational degree-2)
    Type 102 - Composite Curve
    Type 104 - Conic Arc (ellipse/hyperbola/parabola)
    Type 106 - Copious Data (polyline)
    Type 110 - Line (degree-1)
    Type 126 - Rational B-Spline Curve

  Surface entities (→ NurbsSurface):
    Type 108 - Plane
    Type 114 - Parametric Spline Surface
    Type 118 - Ruled Surface
    Type 120 - Surface of Revolution
    Type 122 - Tabulated Cylinder (extrude)
    Type 128 - Rational B-Spline Surface
    Type 140 - Offset Surface
    Type 192 - Right Circular Cylindrical Surface
    Type 194 - Right Circular Conical Surface
    Type 196 - Spherical Surface
    Type 198 - Toroidal Surface

  Topology entities (→ BrepModel):
    Type 186 - Manifold Solid B-Rep Object
    Type 502 - Vertex
    Type 504 - Edge
    Type 508 - Loop
    Type 510 - Face
    Type 514 - Shell

Tests cover: line, arc, cylinder, sphere, cone, torus, plane,
B-spline curve/surface, ruled surface, revolution surface,
tabulated cylinder, copious data polyline, manifold solid B-Rep,
D exponent notation, empty/truncated file handling, and file errors.

茂之钳 4f75bb8b07 feat(brep): S13-B IGES export + format utilities
CI / Build & Test (push) Failing after 33s
Details
CI / Release Build (push) Failing after 39s
Details 
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
