downloadModel method

Implementation

@override
Future<void> downloadModel(ModelSpec spec, {String? token}) async {
  await _ensureInitialized();

  debugPrint('UnifiedModelManager: Starting download - ${spec.name}');

  try {
    await for (final _ in _downloadModelWithProgress(spec, token: token)) {
      // Just consume the stream without emitting progress
    }
    debugPrint('UnifiedModelManager: Download completed - ${spec.name}');

    // Set as active model after successful download (same as Modern API)
    setActiveModel(spec);
  } catch (e) {
    debugPrint('UnifiedModelManager: Download failed - ${spec.name}: $e');
    rethrow;
  }
}
