Description

This PR fixes a bug where DeleteCommand.Result().SuccessCount() and Result().FailCount() return 0 when 404 errors (or other errors) occur during deletion, even though some files may have been successfully deleted.

When using DeleteCommand and encountering errors (e.g., 404 errors when items are already deleted by another process), both SuccessCount() and FailCount() returned 0

solution

Changed to capture the deletion error separately and return actual counts regardless of whether an error occurred.
