//! Module: snapshot command handling.
//! Responsibility: call the generated storage snapshot endpoint and render storage reports.
//! Does not own: stable-memory inspection, endpoint publication, or generic ICP command construction.
//! Boundary: exposes the snapshot command and test-covered report rendering through observability.
