feat: 文档生成 code snippet curl，这个功能什么时候搞上去啊？

### Describe the feature

1

### Environment

11

The issue provides only a screenshot and asks when curl code-snippet documentation generation will be added; it names no files, tests, or entry points. Start by inspecting the screenshot and locating the current documentation-generation flow, then clarify the expected curl output and how completion will be verified.
