Enhancements
- **Detect Missing `tree` Command**: The script now checks if the `tree` command is installed on your system. If not, it provides instructions for installation, ensuring smoother operation.
- **Soft Failure on Clipboard Unavailability**: The script now gracefully handles situations where the clipboard is not available, such as when running over SSH or on systems without clipboard support. This prevents the script from crashing and provides a warning instead.
