- [ ] Create witness service discovery
- [ ] Implement client registration
- [ ] Add notification callback mechanism
- [ ] Create resource monitoring
- [ ] Implement automatic re-registration
- [ ] Add cluster node tracking
- [ ] Create failover coordination

#### 6.3 Integration Points
- Integrate with `CIFSContext` for witness support
- Modify `SmbTransport` for failover handling
