### Feature Description In production deployments, frequent consumer group rebalances (rebalance storm / partition flapping) caused by client network blips, slow startup, or GC pauses induce consumption latency spikes and duplicate message delivery. Operators need historical rebalance event auditing and flapping frequency diagnostics. ### Proposed Solution 1. Introduce `ConsumerRebalanceHistoryReport` model capturing rebalance events, flapping frequency, affected queues, and client churn details. 2. Implement `ConsumerRebalanceAnalyzerService` to detect partition rebalance instability and identify root cause clients. 3. Provide `ConsumerRebalanceAnalyzerController` with `/consumer/rebalanceHistory.query` endpoint. 4. Add frontend `ConsumerRebalanceHistoryModal` visualizing rebalance timeline, flapping severity chips, and stability recommendations. 5. Provide comprehensive controller and service unit tests. -- This is an automated message from the Apache Git Service.
