View Source KafkaEx.SyncGroupRetriesExhaustedError exception (kafka_ex v1.0.1)

Raised when syncing a consumer group fails after exhausting all retry attempts.

Indicates repeated recoverable SyncGroup failures (coordinator errors, timeouts, etc.) during rebalance churn that didn't resolve within the retry window. Distinct from KafkaEx.SyncGroupError, which is raised immediately for a non-recoverable sync failure. Mirrors KafkaEx.JoinGroupRetriesExhaustedError.
