Each worker built the Studio and Talk bundles into the same dist
directory, and the build empties that directory first. A worker that
started, or restarted after a failure, removed the files another worker
was serving, so a Studio spec saw "the style sheet of the add-on could
not be loaded". Build once in a global setup before the workers start.
A run without the setup still builds per worker.
