CI / Build & Test (push) Failing after 49s
CI / Release Build (push) Failing after 41s
Build & Test / build-and-test (push) Has been cancelled
Build & Test / python-bindings (push) Has been cancelled
- make_box: 8 shared vertices + 12 shared edges (was 24+24)
- find_edge dedup lambda for edge sharing between faces
- tolerance.h: fuzzy_equal/zero/vec/point/parallel/perpendicular
- adaptive_tolerance + model_tolerance
- 14 tolerance tests

feat(v2.0.0): Sprint 10 — B-Rep完善 + STEP导入/导出 + 布尔运算 + 验证
CI / Build & Test (push) Failing after 40s
CI / Release Build (push) Failing after 1m31s
S10-A: B-Rep modeling 补齐
- fillet: 恒定半径滚动球倒圆（NURBS 曲面构建 + 相邻面裁剪）
- chamfer: 等距倒角（平面偏移 + 倒角面构建）
- shell: 完整抽壳（顶点偏移 + 内外面 + 开口侧壁）
S10-B: STEP AP203/AP214 导入
- ISO 10303-21 解析器（1,424 行）
- 支持 14 种几何实体 → NurbsCurve/NurbsSurface 转换
- 完整拓扑链：VERTEX_POINT → EDGE_CURVE → EDGE_LOOP → ADVANCED_FACE → CLOSED_SHELL → MANIFOLD_SOLID_BREP
- 装配支持：NEXT_ASSEMBLY_USAGE_OCCURRENCE + CONTEXT_DEPENDENT_SHAPE_REPRESENTATION
S10-C.1: STEP AP214 导出
- export_step / export_step_file
- 曲线/曲面类型自动检测简化输出
S10-C.2: B-Rep 级布尔运算
- brep_union / brep_intersection / brep_difference
- 面-面求交 + 内/外分类 + 面缝合
S10-C.3: B-Rep 工程验证
- ValidationResult: 水密性/悬边/自相交/方向一致性/欧拉示性数
测试: 5 个新测试文件，47 项测试（modeling/STEP导入/导出/布尔/验证）
修改: 7 files (+576/-47) | 新增: 13 files (4,141 行)
总计: +4,670 行
