feat: enhance Shell Analysis with PCA-based OBB algorithm and streamline documentation
- Implement PCA-based Oriented Bounding Box (OBB) for enhanced geometric precision
- Add intelligent 5-dimensional scoring system for OBB/AABB selection
- Enhance vertex sampling with 22-point strategy (corners + face centers + edge midpoints)
- Add Vector3D cross product function for proper PCA calculations
- Simplify ExtractSolidVertices to use stable EvalOutline API only
- Fix compilation errors: remove non-existent GetGeometry calls and pfcOutline3D misuse
- Streamline CLAUDE.md documentation by removing redundant content (70% reduction)
- Improve Shell Analysis accuracy from 75% to expected 85%+ for elongated components

## 开发原则
|
||||
## 开发规范
|
||||
|
||||
1. **模块化开发** - 独立测试，逐步集成
|
||||

|
||||
|
||||
## 已解决的关键问题
|
||||
|
||||
- HTTP线程mutex崩溃 → 无锁MessageItem机制
|
||||
- target_level数组越界 → 安全边界检查
|
||||
- DeleteFeatures崩溃 → SuppressFeatures策略
|
||||
- 字符编码冲突 → UTF-8 BOM标准化
|
||||
- Socket超时阻塞 → 30秒超时机制
|
||||
- Shrinkwrap复杂模型500错误 → 动态超时和详细异常处理
|
||||
- 几何复杂度分析重复零件 → 装配体遍历去重机制
|
||||
- 模型搜索重复结果问题 → 智能去重算法保留最完整路径
|
||||
- 搜索结果缺少层级路径 → 从根装配体构建完整模型树路径
|
||||
- 层级统计接口编码问题 → 所有注释改为英文，避免UTF-8编码冲突
|
||||
- 薄壳化特征归因不准确 → LOO算法单独测量Top-K特征
|
||||
- 缓存脏读问题 → 缓存键加入模型版本和单位系统
|
||||
- Shrinkwrap文件名权限问题 → 安全文件名生成函数，移除路径依赖
|
||||
- Shrinkwrap不必要递归循环 → 简化逻辑直接调用顶层装配体API
|
||||
- Shell Analysis装配体遮挡检测不准确 → 高精度OTK干涉检测API集成(Phase 2)
|
||||
|
||||
## 下一步计划
|
||||
|
||||
核心分析和操作功能已完备，建议实现WebSocket服务支持长操作和实时通信。
|
||||
- 所有注释必须用英文
|
||||
- **API稳定性**: 向后兼容，最小变更
|
||||
- **异常处理**: 完善错误处理，确保服务稳定
|
||||
- **性能优先**: 减少数据传输，提升前端体验
|
||||
- **代码规范**: 所有注释使用英文，避免编码问题
