ViewDesignEngine
352ee39f53
核心设计： - include/vde/vde.h: 统一 C API（50+ 函数，6 种不透明句柄） - 上下文管理 / I/O / Mesh / 曲线 / 碰撞 / 约束求解 / B-Rep / 序列化 - src/capi/vde_capi.cpp: 完整 C API 实现 (240行) - examples/07_capi_integration: C 语言外部调用示例 - CMake: 添加 vde_capi 库 + install 导出支持 模块架构（每个独立 .a）: vde_foundation → vde_core → vde_curves → vde_mesh → vde_spatial → vde_boolean / vde_collision → vde_brep / vde_sketch → vde_capi
