看[SelectionPreviewModel](https://github.com/LuckSiege/PictureSelector/blob/version_component/selector/src/main/java/com/luck/picture/lib/basic/PictureSelectionPreviewModel.java)里面没有提供build方法

Start with selector/src/main/java/com/luck/picture/lib/basic/PictureSelectionPreviewModel.java, which the issue identifies as lacking a build method. Clarify whether preview images should be injectable into arbitrary layers and what API or demo behavior is expected; the issue provides no reproduction or acceptance criteria, so done cannot be verified yet.
