fix: Improve RSS feed fetching with better error handling and user agents
- Added proper User-Agent headers to avoid blocking by RSS servers - Implemented fallback mechanism: HTTP request with headers -> direct feedparser - Extended timeout to 15 seconds for better reliability - Enhanced error logging with detailed feed parsing information - Improved handling of 'bozo' (malformed) feeds with better reporting - Added informative messages for feeds with no new content This resolves RSS fetching issues and improves news aggregation reliability.
