`gws drive files download` reports success but does not create `--output` file

[MattSkala]

gws drive files download returns done: true and a valid downloadUri, but no file is written to the path passed with --output.

Repro:

gws drive files download --params '{"fileId":"...","mimeType":"text/csv"}' --output "csv/test-download.csv"

Expected:
csv/test-download.csv exists and is non-empty.

Actual:
Command prints success JSON (done: true), but csv directory is empty.

Environment:

• macOS 26.4.1
• zsh
