Subject: feat(node): add ".." parent row in file explorer, hide mkdir button
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Show a ".." row at the top of subdirectory listings to navigate back to
the parent. No path traversal risk — currentPath is internal state built
from the node's own index. Hide the mkdir button (not useful yet); update
the upload-controls test marker accordingly.
