Changes Made

Added documentation for markdown.crossCompilerCache in:

  • website/docs/en/api/config/config-build.mdx
  • website/docs/zh/api/config/config-build.mdx

Documentation Details

The crossCompilerCache option was introduced in PR #2256 but was not documented at the time. This PR adds the missing documentation with:

  • Type: boolean
  • Default: true
  • Description: Enables cross-compiler cache for MDX compilation during production builds, caching parsing results across web and node compilers
  • Performance benefit: Approximately 10% faster build times
  • Note: Only takes effect in production builds, inspired by Docusaurus

This PR was written using Vibe Kanban

…的文档。

**添加的内容包括：**

1. **英文文档** (`website/docs/en/api/config/config-build.mdx:270-287`)
2. **中文文档** (`website/docs/zh/api/config/config-build.mdx:272-289`)

**文档说明：**
- 类型：`boolean`
- 默认值：`true`
- 功能：在 `rspress build` 时启用跨编译器缓存，通过在多个编译器（web 和 node）之间缓存 MDX 解析结果来加速生产环境构建
- 效果：构建时间减少约 10%
- 限制：仅在生产环境构建时生效
- 灵感来源：Docusaurus
