Integration: --list no longer shows test description

I can see the behavior of `-l --list` has been changed to show tags instead of description.

However I don't use tags, but I'd love to see description back next to the test name. Do you plan to show them both?

Start at the `-l`/`--list` command handling and trace how test names, tags, and descriptions are assembled for output. Confirm the current behavior and determine where the listing format is defined. Done means the list shows descriptions alongside test names while retaining the existing tag output.
