Summary

This PR adds SEO metadata support for documentation pages through a special comment syntax in Markdown files.

Changes

• Added SEO metadata parser that extracts metadata from //[doc-seo] comment blocks in documentation files
• Implemented support for custom Description meta tag
• Metadata is defined in JSON format within the comment block

Usage

Documentation authors can now add SEO metadata at the beginning of their Markdown files using the following syntax:

```json
//[doc-seo]
{
    "Description": "Custom page description for SEO"
}
```

The parser will extract this metadata and apply it to the page's meta tags, improving search engine visibility and social media sharing.
