Answering on a port was the only evidence callers had that they had reached
the authoritative hub. A local cache and central both served port 8000,
separated only by IP family, and every default reached the cache for seven
weeks (ADR-010).

Adds instance_role and instance_label, surfaced on /state/health. The default
is "unknown" on purpose: an instance that has not declared itself is not the
primary. Production values declare primary/railiance01; the chart default
stays unknown because a chart can be installed anywhere.

statehub status now prints which instance answered.
