Expose consumer group state as a gauge metric encoded as an integer. This allows monitoring and alerting on group state transitions (e.g. rebalancing, dead groups). Mapping: Unknown=0, PreparingRebalance=1, CompletingRebalance=2, Stable=3, Dead=4, Empty=5, Assigning=6 (KIP-848), Reconciling=7 (KIP-848) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
