- Fixed import error by restoring proper NewsFetcher class structure
- Updated RSS feed fetching implementation with improved error handling
- Enhanced feed parsing with better timeout management and user agents
- Maintained compatibility with existing system architecture
- Resolved server startup issues caused by missing class definition
- Added proper User-Agent headers to avoid blocking by RSS servers
