Add debug test scripts for troubleshooting

Added two diagnostic tools:

test_mention.py:
- Tests MentionDetector with various message formats
- Shows nickname generation (Kene from Kenearos)
- Displays extracted content from mentions
- Helps verify mention detection is working correctly

test_irc.py:
- Minimal IRC bot for testing message reception
- Prints all received messages to console
- Helps diagnose if IRC connection is receiving messages
- Useful for debugging connection issues

These tools help troubleshoot when bot doesn't respond:
1. Run test_mention.py to verify detection logic
2. Run test_irc.py to verify IRC message reception

test_irc.py
