docs: add Chinese translations for documentation

- Add development.mdx (开发指南)
- Add troubleshooting.mdx (故障排除)
- Add features/index.mdx (功能概览)
- Add features/authentication.mdx (身份验证)
- Add features/java.mdx (Java 管理)
- Add features/mod-loaders.mdx (模组加载器)

All translations maintain technical terms in English while translating content to simplified Chinese
