Describe this repository's build with a build definition

Its own `.werkator.yml` still used the deprecated `branches` section
with an `autoBuild` schedule that was switched off. That section is read
only while nothing defines a build at all, and step 18 rejects it by
name — so this repository would have blocked the precondition of that
step, which asks that no configuration still in play carries it.

Nothing about the build changes: `builds.default` with `trigger.onPush`
is a build of every new commit on every branch, which is what the branch
section said. `config:print --full` resolves the definition completely
and logs no deprecation warning any more.
