fix: normalize Chinese (zh-CN) documentation language and terminology #13504

Description

The Chinese (zh-CN) documentation contains inconsistencies in character encoding and terminology:

1. Mixed traditional and simplified Chinese characters - Some terms use traditional characters (運, 儲, 據) mixed with simplified Chinese
2. Translation typos - Several mistranslated terms (e.g., "上市" instead of "列出", "全域性" instead of "glob")
3. Inconsistent terminology - Technical terms are not uniformly translated across different documentation files
4. Incorrect internal anchor links - Some internal links reference non-existent anchor IDs
   These inconsistencies reduce readability and create a poor user experience for Chinese-speaking users.

Steps to reproduce

1. Visit zh-CN documentation: https://opencode.ai/docs/permissions (or any zh-CN doc page)
2. Observe mixed traditional/simplified Chinese characters in the content
3. Specific examples:
   • In permissions.mdx : "運行" appears instead of "运行"
   • In tools.mdx: "巴什" appears instead of "bash"
   • In plugins.mdx: "運行" appears instead of "运行"
     For developers: Navigate to packages/web/src/content/docs/zh-cn/ in the codebase and open any of the 17 affected files to verify the issues.

Affected documentation pages

• Permissions: https://opencode.ai/docs/zh-cn/permissions/
• Tools: https://opencode.ai/docs/zh-cn/tools/
• Models: https://opencode.ai/docs/zh-cn/models/
