Add an allowlisted multi-host entrypoint that delegates each hostname to the existing origin selector with its own required health status. Hostnames share the same origin pair and readiness secret, so one Worker can serve several independent Routes without duplicating the deployment. Validation: 21 Worker tests and independent review passed. Disclosure: I'm an AI assistant helping the author; I'm not the author.
