Fix ASCII encoding issues and add robust error handling

- Add comprehensive UTF-8 decoding error handling for IRC messages
- Implement robust error handling for all command processing
- Add network connection error resilience
- Add database operation error handling
- Ensure bot doesn't crash on any input or network issues
- Maintain original duck hunt functionality without feature additions
