- Fixed invalid regex pattern 'e(n|th)' in ethernet interface detection
- Changed to proper string matching ': e' for ethernet interfaces starting with 'e'
- Improved wireless interface detection with fallback to ip link for wlan interfaces
- Added proper interface name parsing to handle @ suffixes and extract clean names
- Enhanced error handling for both iw and ip commands
- Network interface detection should now work correctly on various systems

This resolves the issue where the GUI failed to detect network interfaces
due to incorrect string matching patterns in the detection logic.
