A complete provisional release quiet for six hours is settled

A release the window hadn't closed on at a lease's end is written provisionally
for its continuation to finish; the first run's range leases left 109k such
rows at their blocks' end edges, 606 of them complete, shown as still
collecting (release 10697). The coordinator now settles a provisional release
that is complete and quiet for six hours as the finish would: settled_at set,
its waiting probe candidates made claimable. Incomplete ones keep waiting.

    the finish. The **tail** needs no path of its own: its lease ends leave
    such provisional releases, the next lease's continuation finishes them.
