cleanupStorage method

@override Future<int> cleanupStorage()

Clean up orphaned files

⚠️ This deletes files! Call getOrphanedFiles() first to see what will be deleted.

Returns number of deleted files.

Implementation

@override
Future<int> cleanupStorage() async {
  await _ensureInitialized();

  gemmaLog('UnifiedModelManager: Cleaning up storage (explicit user call)');

  // Propagate real errors instead of returning 0: this is a destructive op,
  // and a mid-sweep failure that already deleted some files must not report
  // as "0 removed" (indistinguishable from "nothing to clean").
  final protectedFiles = await _getProtectedFiles();
  final deletedCount = await ModelFileSystemManager.cleanupOrphanedFiles(
    protectedFiles: protectedFiles,
    enableResumeDetection: true,
  );

  gemmaLog('UnifiedModelManager: Cleaned up $deletedCount orphaned files');
  return deletedCount;
}
