CopySpeak v0.0.3

Fixed

• KittenTTS installer now works on clean Windows 11 without Python pre-installed
  • Embeds installer scripts in binary and extracts to temp directory at runtime
  • Auto-detects any Python 3.x version, offers winget installation if not found
  • PowerShell window now visible with success/failure feedback before pause
  • Default config changed from py -3.12 to python (no version pinning)
