Select the migration steps to run for a world, in ascending version order.
A step runs when from < step.version <= to — the lower bound is exclusive
(the world already has from) and the upper bound inclusive (migrate up to and
including the running system version). An empty from behaves as 0.0.0
(runs everything up to to); an empty to yields no steps (the target version
is unknown).
