When the search provider returns a link like 'shinobi-no-ittoki' instead of
'/anime/stream/shinobi-no-ittoki', the key was not being extracted and all
folders were marked as unresolved.
Now handles both link formats:
- URL format: '/anime/stream/key' -> extract key
- Direct format: 'key' -> use as-is
Also added debug logging for both resolution paths to aid troubleshooting.
