feat: Implement cutout tool and depth generation features

- Added a new cutout tool for selecting regions in images, allowing users to choose mesh shapes based on selected areas.
- Introduced depth generation capabilities for rasterized images, including normal data extraction.
- Created jobs for generating depth planes and region data, enhancing the AI data generation workflow.
- Developed a selection refinement process for cutout regions, improving accuracy in generated outputs.
- Established a new region module for handling rasterized image regions and their associated AI generation tasks.
- Enhanced node graph builders for asset generation, facilitating smoother integration of new features.

 ## 命名规范
 
 - 变量、函数、Docstring 使用英文；同一概念在代码和文档中使用统一表达
+- 功能代码的动作前缀应表达产物边界：`generate_*` 表示 AI 生成，`build_*` 只在内存中构建值或几何，`create_*` 表示创建 Blender Image、Mesh、Material、Object 等真实数据
 - 名称应说明业务职责，并与用户概念、公开协议和界面术语保持一致；不要使用脱离上下文后无法判断用途的宽泛名称
 - 文件和目录名应反映职责层级：集合层使用复数，单个功能或动作使用单数或动宾结构；同一层级保持一致
 - Python 类使用大驼峰，不添加项目名前缀。Operator 使用动宾结构，如 `ConvertToDepthPlane`、`RemoveImageBackground`；Menu、Panel、AddonPreferences、PropertyGroup 分别使用实际类型后缀，如 `AnyImageImageMenu`、`ServerPanel`、`AnyImagePreferences`、`AnyImageSettings`
