- [ ] Implement lease epoch tracking for v2 leases

#### 1.3 Integration Points
- Modify `Smb2CreateRequest` to include lease contexts
- Update `SmbFile` caching logic to use leases
- Add lease break handling in `SmbTransport`

### Phase 2: Persistent Handles
**Priority: HIGH** | **Estimated Effort: 4-5 weeks**

Persistent handles allow connections to survive network interruptions and server failovers.
