MeshFactory：程序化几何单一源 + CreatePrimitive 链路

Browse Source 
新增 MeshFactory（Cube/Plane/Sphere/Cylinder/Cone/Torus + 切线计算），
Model 程序化几何改走 MeshFactory（收敛为单一几何源，消除重复的顶点
生成），并新增 CreatePrimitive；打通 AssetManager/IAssetUploader/
VulkanAssetUploader 的 CreatePrimitive 链路；编辑器 Procedural 弹窗
下拉 + ResolveProcedural 伪路径反解 + 场景序列化（程序化图元可存取）。
