Add auto-generated RSS feed with scheduled publishing support

- Created /rss.xml API route that generates valid RSS 2.0 XML
- RSS feed integrates with scheduled publishing system automatically
- Includes full post content, proper metadata, and CDATA encoding
- Added RSS feed link to HTML metadata for auto-discovery
- RSS link already exists in blog footer navigation
- 1-hour caching with error handling and fallback RSS
- Feed updates automatically when new posts go live

Features:
✅ Works with scheduled posts (future posts excluded)
✅ Proper XML escaping and CDATA content encoding
✅ Rich metadata including author, categories, publish dates
✅ Auto-discovery via HTML <link> tags
✅ Graceful error handling with fallback feed
