Drop the two companion tests from #106124 and #106099 that already pass
on main without their fixes (a pinned active transcript is never measured
because prune() skips it before weighing; a rerendered effect already
discards the previous closure). Keep the one red-on-main invariant per
fix: no re-serialisation of unchanged warm transcripts, and change ticks
coalescing behind an in-flight session.active_list request.
