Expand description

Download an installer into a temporary file and verify it before finalizing.

The payload is streamed to a .part file next to download_path, with progress forwarded through the provided callbacks. If the installer hash is present, it is verified as the bytes arrive. On success, the temporary file is atomically finalized into download_path and the set of tolerated legacy checksum algorithms is returned to the caller.

When any step fails, the temporary file is removed so the install flow does not leave behind partially downloaded payloads.
