## Summary
This PR introduces a Cluster Multi-Dimensional Health & Master-Slave
Inspection Framework for RocketMQ Dashboard to proactively detect operational
risks.
### Highlights
1. **Multi-Axis Inspection Engine**:
- **Broker Master Availability**: Scans all broker groups for missing
Master (ID=0) nodes.
- **Disk & Memory Hazards**: Inspects CommitLog disk space ratios with
configurable warning thresholds (>85%).
- **Master-Slave Pair Verification**: Evaluates synchronization pairing
and single point of failure (SPOF) risks.
- **Topic Routing Skew**: Identifies user topics assigned to only one
broker group in multi-broker clusters.
2. **Scoring & Reporting Model**:
- Computes weighted cluster health scores (0-100) and issue severities
(`INFO`, `WARNING`, `HIGH`, `CRITICAL`).
- Accompanied by remediation recommendations.
3. **Frontend Diagnostics Console**:
- Built `ClusterInspectionModal.jsx` to render health score cards, issue
summary tables, and broker sync matrices.
## Test Plan
- Evaluated score degradation rules against mock broker runtime failures and
single-broker topology setups.
