实现Creo薄壳化分析功能 - 基于真实几何边界算法

新增薄壳化分析接口 POST /api/creo/analysis/shell，实现CAD模型内部特征识别和删除建议。

技术突破：
- 使用OTK pfcOutline3D API实现真实几何包络盒计算
- 基于边界识别法构建外壳特征白名单
- 实现标准置信度计算和特征安全性评估算法
- 支持零件和装配体的完整薄壳化分析
- 完全移除假数据和模拟计算，实现纯几何分析

API功能：
- 返回安全删除、建议删除、保留特征的完整分类
- 包含特征ID、名称、类型、置信度、体积减少预估
- 正确显示partFile和partPath信息（含扩展名）
- 支持层级路径显示和文件信息追踪

已解决问题：
- 修复特征名称格式（EXTRUDE_1等标准格式）
- 修复路径显示问题（保留文件扩展名）
- 解决编译错误（中文字符串问题）
- 实现与层级分析接口一致的数据格式
