- 新增XCAF转换器，直接从STP到GLB保留完整装配层级 - 修复HTTP API与CLI参数不一致问题 - 修复静默吞没错误的问题，遵循快速失败原则 - 清理旧文件，整理测试文件到tests目录 - 添加URL下载支持，可直接转换远程STP文件 - 更新文档，准确描述XCAF装配保留功能 技术改进： - 使用STEPCAFControl_Reader读取带装配信息的STEP文件 - 通过RWGltf_CafWriter直接导出GLB，无需STL中间格式 - 支持CPU多线程并行三角化 - HTTP API和CLI使用完全一致的转换参数 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
