fix(store): a returned optimistic guess is the keyed diff; landings keep keyed rows while guesses are out (#4737, #4738, #4739) (#4740)

* fix(store): a returned optimistic guess is the keyed diff; a landing keeps keyed rows while guesses are out (#4737, #4738, #4739)

A setter that returns a new array on an optimistic family is now
written into the draft as the keyed diff (a same-key row recurses into
its own draft), so it makes the writes the field edit would: one write
per changed row, never an arrangement guess on the list (S-59). Before,
the return became a list guess that list readers entered: a guess made
during its refresh waited for that refresh (#4739), and the refresh's
failure never reached Errored (#4737).

While guesses are out, the derive's new object under a keyed row's key
is paired with that row's target, not only a guessed row's. A row whose
guess settled lost its target at the next landing, so a later guess
went to a row the screen no longer showed (#4738).
