- [ ] Implement directory metadata caching
- [ ] Add directory change notification integration
- [ ] Create parent-child lease relationships
- [ ] Implement directory lease break handling
- [ ] Add directory enumeration caching

#### 4.3 Integration Points
- Extend `SmbFile` for directory lease support
- Modify directory listing operations for caching
- Update change notification handling
