Cursor Agent dfebd7f9e6 fix: syntax error in downloads_provider.dart
Fixed duplicated code that caused compilation error:
- Removed duplicate _setError method definition
- Fixed parameter list: void _setError(String? error, [String? stackTrace])
- File now compiles correctly

Error was:
lib/presentation/providers/downloads_provider.dart:173:2: Error: Expected a declaration, but got '?'.
}? error) {
 ^

Fixed by properly replacing the old method with new signature.
