KIP-1191 — Dead-letter queues for share groups

Accepted Consumer

Adds dead-letter queue (DLQ) support for share groups, automatically routing records that exceed their max delivery count or are explicitly rejected (ARCHIVED acknowledgment type) to a configurable dead-letter topic. KIP-932's share groups track delivery counts and enforce limits, but provided no automated mechanism to handle poison messages—they simply accumulated redeliveries until manually addressed.
