Restores the checkpoint's process state and replays the open path from its
root, as if the person walked it again by tapping: the root's own enter
flow, then every screen of the navigation chain, each edge recomputed over
fresh data (a fresh token, a fresh item lookup) — the same replay a retrace
runs, with the library doing the tapping. It sends the screens' own
enter flows and returns the fresh top screen's handle.
