🔧✨ Handle nil case for selectedDir and selectedDirCell

- Added a check to handle the case when `selectedDir` and `selectedDirCell` are nil in `fileItemSelected` method.
- If either `selectedDirCell` or `selectedDir` is nil, it returns early from the method.
- This change ensures that the program won't crash when trying to access properties of nil values.
