A Kafka cluster's KRaft controller pods are named "<release>-c-<hash>-<id>" (8-hex hash, id at least one digit), and that derived pod hostname must fit the 63-char DNS-1123 label limit. That is tighter than the 53-char Helm release-name budget validateNameLength enforced, so a release name of 51-53 characters was admitted but then failed the chart render (kafka.assertNameLength) forever, an un-recoverable upgrade dead-end for an existing cluster whose name is immutable. Cap the Kafka app name at admission, mirroring the existing Kubernetes worker-pool cap, so the overflow surfaces on the Kafka CR the operator is editing instead of at render time on a pod Strimzi can never create. The chart's render guard remains the second line of defense and also catches larger clusters whose higher node ids need more digits. Signed-off-by: Alexey Artamonov <aleksei.artamonov@aenix.io>
