Implements CUST-WP-0070-T02. publication joins DURABLE_FLAVORS, so CATEGORIES
picks it up automatically; classification.py and the cli --category choices are
updated to match canon v1.1.
A published corpus of authored records previously had to be filed as project —
the only non-durable category — implying eventual retirement of something meant
to be kept. Repos with no classification file at all fell through to
flavor=tooling.
Full suite: 161 passed.
