 * or when no {@link WorkerVariablesContext} provider is mounted; returns the
 * cumulative list (with field-update deltas applied) once the first update
 * arrives.
 *
 * Subscriptions are ref-counted by worker key so multiple consumers targeting
 * the same worker share a single underlying `subscribeToFieldUpdates` call.
