  `ctx.stash` key under which the prior-iteration primitive snapshot is kept for
  {@link @nhtio/adk!PreservationRule} statefulness — see the plan's
  "Statefulness for `PreservationRule`" section. Exported (as
  `ORDERING_GUARD_SNAPSHOT_STASH_KEY`) so a caller can pass a custom
  `options.snapshotStashKey` without guessing the default's exact string.
