feat: prioritize OpenGraph tags for metadata extraction

Browse Source 
- Extract title with priority: og:title > twitter:title > <title>
- Extract description with priority: og:description > twitter:description > meta description > first <p>
- OpenGraph tags provide better, curated metadata for sharing
- Twitter Card tags as fallback for social media compatibility
- Improved metadata quality for most modern websites
