- [ ] Implement handle state serialization
- [ ] Create reconnection logic with handle replay
- [ ] Add timeout management for durable handles
- [ ] Implement handle lease association
- [ ] Add persistent handle capability negotiation
- [ ] Create handle cache for reconnection

#### 2.3 Integration Points
- Extend `SmbFile` with persistent handle support
- Modify `SmbSession` for handle replay during reconnection
