CI / Build & Test (push) Failing after 35s
Details
CI / Release Build (push) Failing after 43s
Details 
- exact_predicates: 匿名namespace泄漏导致orient_2d符号不可见
- mesh_quality: 纵横比公式归一化到[0,1], 1=等边三角形
- r_tree: insert/remove自赋值导致STR rebuild后数据丢失
- test_distance: PointToLine测试点在线上的错误断言
- test_smooth: 边界值断言从_LT改为_LE
- test_quality: 归一化纵横比的期望值调整

ViewDesignEngine 8ae4b86e08 feat: GMP 精确算术后端 + 可插拔谓词接口
CI / Build & Test (push) Failing after 38s
Details
CI / Release Build (push) Failing after 28s
Details 
新增:
- include/vde/foundation/exact_predicates_gmp.h: GMP 精确谓词
  - orient_2d/3d, in_circle 完全精确（mpq_class 有理数）
  - 零舍入误差，任意精度
- include/vde/foundation/predicates.h: 统一谓词接口
  - Predicates<T> 编译期选择后端
  - VDE_USE_GMP=ON → GMP, OFF → 自适应 double
  - 便捷函数: orient(), in_circle()
- cmake/FindGMP.cmake: GMP 查找模块
- CMake: -DVDE_USE_GMP=ON 启用 GMP 精确模式
- AdaptiveDouble 包装器: 统一后端接口

使用:
  cmake -DVDE_USE_GMP=ON ..  # 完全精确模式

ViewDesignEngine 029dd6b75a feat: v0.6.0 精度提升 — Shewchuk Level C + 分层容差 + 业内方案调研
CI / Build & Test (push) Failing after 31s
Details
CI / Release Build (push) Failing after 31s
Details 
精确谓词: Shewchuk Level B → Level C (expansion arithmetic)
  - Dekker split + Two-Product + Two-Sum + Expansion 4-component
  - orient_2d/3d 自适应精度，支持大坐标(>1e14)
  - in_circle 扩展精度

容差系统: 单级 → 分层
  - Tolerance::tighten/relax 继承
  - Tolerance::min 合并取更严格
  - ToleranceScope 作用域临时容差
  - 预设容差级别: Modeling/Fitting/Intersection/Snapping

文档: 新增 06-精度提升方案调研 (252行)
  - 6种主流精度方案对比
  - Parasolid/ACIS/OCCT/CGAL 商业内核解密
  - VDE v0.6-v2.0 精度提升路线图
