Spot2YTMusic v0.1.1

This fixes a Windows packaging error in v0.1.0. Exportify ZIP import worked, but Scan all stopped before making any YouTube Music changes because the EXE was missing the library's language files.

The EXE now includes those files. Every Windows build also starts the frozen app and initializes its YouTube Music client, so this error is caught before release. Background errors now say which step failed.

I checked the import worker with a multi-playlist Exportify ZIP. Download the new EXE or Windows ZIP below. The EXE remains unsigned, so Windows may show a publisher warning.
