Follow-up to #56. The tail-cancel condition counted only in-flight tasks, but with
--rolling-start-sizegroups are submitted in waves, early in a rollout few groups are in flight simply because most haven't been submitted yet, so the condition fired at the start and cancelled the whole batch.Compare tail_cancel_groups against total remaining work instead: unsubmitted groups plus in-flight tasks. Without rolling start everything is submitted upfront, so behavior is unchanged.
