/// Declarative restart policy that the daemon stores on a created container.
///
/// The shape mirrors the in-flight upstream proposal in
/// [apple/container#1258](https://github.com/apple/container/pull/1258):
/// a bare `String`-backed enum with the conservative initial set
/// (`no`, `onFailure`, `always`). Bounded `on-failure:N` retries and
/// `unless-stopped` are intentionally deferred — they ship as separate
/// follow-ups once #1258 lands.
///
/// At present this is a data-shape only contract on the fork: the policy is
/// recorded in ``ContainerCreateOptions/restartPolicy`` but the daemon does
/// not yet observe container exits and re-launch per policy. Enforcement
/// will arrive via the upstream restart manager (#1258).
