Introduce worker.bstein.dev as the canonical hostname for the owner-only
Hermes coordinator, previously agent.hermes.bstein.dev.
The rename is additive, matching the shape #38 restored for chat and triage.
CoreDNS, both agent Ingresses and the hermes-sites certificate now serve BOTH
names, so merging this cannot take away the endpoint the operator uses to
reach the coordinator. Retiring agent.hermes.bstein.dev is a separate,
separately scheduled change. No redirect middleware is added.
What switches to the new host:
- HERMES_DASHBOARD_PUBLIC_URL and the oauth2-proxy --redirect-url
- the Keycloak agent proxy rootUrl
- operator docs, skills, the ZAP baseline target and the triage monitor default
What stays dual-homed until retirement:
- CoreDNS hosts entry, both agent Ingress rules, certificate SANs
- API_SERVER_CORS_ORIGINS (now a comma-separated pair)
- the Keycloak redirect URIs, web origins and post-logout origins, so a
rollback only needs the oauth2-proxy --redirect-url reverted and does not
require re-running the ensure job
The agent client passes its legacy origin through the optional fourth argument
#38 added to ensure_proxy_client, so no second mechanism is introduced. The
immutable ensure Job goes -11 -> -12 because #38 already consumed -11 and that
run has completed; without a further bump this change would never be applied.
Login on the new host fails until the -12 Job completes.
Because the session and CSRF cookies use the __Host- prefix they are bound to
one origin, so a fresh login must start on worker.bstein.dev and existing
sessions do not carry over -- re-login is required after rollout.
#38's public-host continuity test now covers the agent proxy's dual origins
rather than asserting the agent surface was untouched by the rename.

Red-build to green-rebuild is 1m04s on Ariadne 0.1.0-402, down from 4m00s
armed-to-resolved when the repair spawned its own Kubernetes Job. Reframe the
timings around the red build, since the arming leg depends on the agent pool.
