Add and remove customer domains

Use safe idempotency without silently claiming domains from another resource.

domain-lifecycle.ts

const domain = await domains.add("app.customer.com");
await domains.remove(domain.hostname);

Repeated adds return current state only when the adapter can prove the domain belongs to the configured project, zone, environment, or service. Another owner throws DOMAIN_CONFLICT. Repeated removal succeeds when already absent and does not cross provider scope.
