Cursor/continuous integration failures 477d

[lucaspar]

Note

Low Risk
Refactor and typing/test adjustments only; download and upload logic paths are unchanged aside from clearer variable scoping.

Overview
Small SDK cleanup aimed at continuous integration failures, with no intended behavior change for downloads or uploads.

In Client._download_files, total_bytes_total is now set only inside the list vs paginator branches (byte-level progress when the file source is a list; None and the fallback path for a Paginator). The completion log still uses the same variables after both branches.

GatewayClient.upload_new_file widens the file_ptr type to BinaryIO | _ProgressFileReader so type checkers accept wrapping the file handle when a progress_callback is used.

test_download_fails_for_invalid_files drops capsys and stderr checks for "simulating download", keeping assertions on Result success/failure and error payloads.
