//! Snapshot/restore. VZ gates `saveMachineStateToURL:` and
//! `restoreMachineStateFromURL:` behind `#if defined(__arm64__)` in the
//! SDK headers, so on Intel hosts these symbols don't exist. We mirror
//! that with a `cfg(target_arch = "aarch64")` split.
//!
//! On non-aarch64 builds, callers that hit the snapshot path receive
//! [`crate::Error::SnapshotUnsupported`].
