--quiet suppresses failing git-hook output in CI logs

[skwakl]

Describe the bug

Great to see PR #1840 merged—thanks for the improvement!
When running devenv --quiet test the error messages from failing git hooks are not printed.

To reproduce

1. Set up a devenv with a failing git-hook.
2. Run devenv ci --quiet
3. Observe that the hook fails silently—no error details are shown in the output.
