Revert the timeline optimistic and pagination rework (#2596)

* Add npm release track invariant and beta dist-tag procedure * Revert "Keep older chat history and image previews stable (#2490)" The timeline optimistic/pagination rework needs more work than main releases can wait for. Reverted together with #2484; both are reapplied on integration/timeline-optimistic-rework. * Revert "Stop completed turns from appearing stuck (#2484)" See the #2490 revert. #2490 built on this submission-authority change, so the two revert and reapply as a pair.
