/**
 * Registers a service and, optionally, initializes the Datadog RUM SDK.
 *
 * Any caller may pass `application`. The first call that includes it
 * initializes the SDK; subsequent callers' `application` config is ignored
 * with a warning. Callers that omit `application` register their service
 * without attempting SDK init.
 *
 * Returns a `RumServiceRegistration` — `{ cleanup, setServiceContext }`.
 * `cleanup` removes this service's `beforeSend`, `allowedTracingUrls`, and
 * persistent context. `setServiceContext` attaches session-lifetime metadata
 * to every event whose `event.service` matches this service's name.
