Unable to enable spread verbose with charmcraft test

[carlcsaposs-canonical]

Bug Description

Expected behavior

When running charmcraft test, it is possible to pass -vv to spread to always see output

you'll see the output locally since the task failed (-vv to see the output nevertheless).

from https://github.com/canonical/spread?tab=readme-ov-file#hello-world

On GitHub Actions, spread is always run with a single job so we always want to see output of that job

Actual behavior

It is not possible to pass -vv to spread when using charmcraft test

To Reproduce

charmcraft test 'github-ci:ubuntu-latest:tests/spread/test' -vv
charmcraft test -- 'github-ci:ubuntu-latest:tests/spread/test' -vv
charmcraft test 'github-ci:ubuntu-latest:tests/spread/test' -- -vv

Environment

Ubuntu 24.04 github runner

charmcraft.yaml
