 * Normalize the runtime shape of `admin.fetchTopicMetadata`'s response to
 * a bare `ITopicMetadata[]` regardless of which surface the
 * `@confluentinc/kafka-javascript` layer happens to return today. The
 * `.d.ts` declares the call as `Promise<{ topics: Array<ITopicMetadata> }>`
 * but the runtime resolves with the bare array — long-standing mismatch
 * tracked at confluentinc/confluent-kafka-javascript#367. Handle either
 * shape so a future library fix doesn't require code change at the call
 * sites.
 *
 * TODO(#514): delete this normalizer (and its call sites' workarounds)
 * once the upstream issue is fixed and we pick up the library version
 * whose runtime aligns with the declared type.
