### Feature Description In dual-DC (Active-Active) and multi-cluster disaster recovery architectures, configuration drift across clusters (e.g., mismatched read/write queue numbers, perm settings, or topic sysFlag) leads to silent message production failover drops and uneven traffic routing. Operators need an automated cross-cluster topic comparison, drift detection, and rectification pipeline. ### Proposed Solution 1. Introduce `TopicCrossClusterSyncReport` model tracking topic attribute diffs across source and target clusters (readQueueNums, writeQueueNums, order, perm). 2. Implement `TopicCrossClusterSyncService` to diff topic metadata between clusters and generate synchronization action plans. 3. Provide `TopicCrossClusterSyncController` with endpoints for drift query and rectification execution. 4. Add frontend `TopicCrossClusterSyncModal` visualizing attribute differences and one-click configuration alignment. 5. Provide comprehensive controller and service unit tests. -- This is an automated message from the Apache Git Service.
