Pull request overview
Adds support for registering a USM Connect cluster using a new --kafka-cluster flag (in addition to the existing --confluent-platform-kafka-cluster), including updated help text and integration fixtures.
Changes:
- Add
--kafka-clusterflag tousm connect register, making the two Kafka cluster flags mutually exclusive and requiring one of them. - Introduce a “hybrid” output shape for the
--kafka-clusterflow. - Update integration tests and golden outputs to reflect the new flag behavior and validation errors.

- The --kafka-cluster path still flows through the on-prem→cloud Kafka ID mapping and the "not found" logging. For cloud IDs like "lkc-...", this will always miss the map, log a misleading error on success, and can even fail early if ListUsmKafkaClusters requires permissions (even though the mapping is irrelevant for --kafka-cluster).
if cmd.Flags().Changed("kafka-cluster") {
kafkaClusterId, err = cmd.Flags().GetString("kafka-cluster")
if err != nil {
return err
}
}

Can we check with the cli team is it is okay to remove this flag altogether?
or is the recommendation to deprecate this first?
