## Summary
This PR adds a Topic Lifecycle Governance & Zombie Audit Service to RocketMQ
Dashboard to eliminate orphaned topics and optimize queue resources in
enterprise RocketMQ deployments.
### Main Features
1. **Lifecycle Audit Engine**:
- **Orphan Topic Detection**: Detects topics with 0 active consumer group
subscribers.
- **Zombie Topic Identification**: Identifies unused/abandoned topics
that can be safely archived.
- **Oversized Queue Allocation Warning**: Highlights low-throughput
topics allocated with excessive queue counts (>32 queues).
2. **Audit Reporting**:
- Implemented `TopicGovernanceReport` providing aggregated counters and
actionable remediation tips.
3. **Frontend Dashboard Modal**:
- Built `TopicGovernanceModal.jsx` displaying categorized governance
findings and action items.
## Test Plan
- Verified topic auditing logic against system topics, retry topics, and
custom user topics.
