"""`da sync --quiet` truly suppresses stdout chatter, including the download
loop and final summary.

Without --quiet, the same fixture prints "Downloading", "Downloaded:", etc.;
with --quiet, stdout stays empty and the terse one-liner lands on stderr.
The first test forces the download loop to run so the contrast between
noisy/quiet stdout is observable (mutation-tests the flag — see PR #145
for the original empty-manifest test that passed even without --quiet).
