feat(collect): add --toDate upper bound for zomb-eh re-queue branch

Mirrors --fromDate: bounds the zomb-eh periodic re-queue branch by
PostDate <= the given date. Stacks alongside --fromDate and the
cooldown clause rather than replacing either, so --fromDate/--toDate
and --force can all be combined, and each applies with or without
--force.

Named --toDate rather than --end to pair with --fromDate -- --start
already exists as an unrelated flag (resume folder traversal at a
blog name).
