Six lists rebuilt themselves as a whole new screen every round, because their
content is data: an editor's rows carry a staged `current → new` value, its
title counts what is staged, the outbox loses the message it just sent, the
watchtower's log rewrites the row you acknowledged. Each approximated the cost
with `default=cursor`, which recovers only the cursor, and only while the row it
names still exists — the typed filter went every time.
SelectScreen.replace_items swaps the rows (and optionally the title) in place
instead. The place is kept by value, so the highlight lands back on its row
wherever that row moved to, and falls back to the same position in the list when
the row is gone entirely — which is what you want after deleting the row you
were sitting on. The filter rides along.
So the config editor, device actions, the channel manager, the courier outbox,
the watchtower and the repeater-admin editor all hold one screen for the whole
visit now, refreshed after each action. The courier's ticker is started once for
the visit rather than per round, and folds a flow's effect in immediately rather
than waiting up to a second for the next tick.
The admin node picker gains a `stay` form. Repeater admin used to draw a second,
identical SelectScreen as a static backdrop so the password prompt had something
behind it, then drop the list before the session; the real list stays up through
both now — so cancelling the password lands back on the node list rather than
bowing out of the flow, and leaving a node's admin session lands there too.
Administering two repeaters in a row is an Esc and a pick.
