asset
Create 3D geometry parametrically, arrange along paths or in batches, undo actions, and save subtrees as prefabs. Also lists available shapes and materials.
Instructions
参数化 3D shape 生成（11 shape）+ 路径阵列 + batch + undo + save 预制件。create/path/batch/undo/save 经 editor 持久化（视口可见、可 undo）；list_shapes/list_materials 静态返回。
