Fix Visual Basic language parsing in top command
- Fixed issue #54 where "top Visual Basic" command was not working - The problem was that split(r"\s+", ...) was incorrectly breaking "Visual Basic" into ["Visual", "Basic"] - Added new parse_programming_languages() function to utils.py that properly handles multi-word languages - Updated top_langs() method in commands.py to use the new parsing function - Added comprehensive tests demonstrating the fix in experiments folder The fix ensures that "Visual Basic" is treated as a single language name, allowing the bot to correctly find users who have "Visual Basic" in their profiles. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
