Fix: Prevent duplicate workflow runs for issues opened with enhancement label

- Check if opened event has enhancement label already present
- Skip opened event if label exists (labeled event will handle it)
- Set cancel-in-progress: true to cancel older runs
- Prevents duplicate runs when both opened and labeled events fire
