✨ [feat] Add new ANSI art files and enhance filename normalization

 - 📁 Added new ANSI art files for Star Wars characters:
   - `ANSI_Star_Wars_WZ - Helmets.ans`
   - `ANSI_Star_Wars_WZ - Wookie.ans`
   - `ANSI_Star_Wars_ndh - darth.ans`
   - `ANSI_Star_Wars_ndh - r2d2.ans`
   - `nu - orbital - orbital.ans`

 - 🛠️ Updated `Restore-UnusedAnsiFiles.ps1` script:
   - Improved filename normalization by:
     - Removing spaces around hyphens and dashes (e.g., "1998 - 08" -> "1998-08")
     - Removing any remaining spaces for cleaner filenames
