Reading the last status back from the transcript -- added so a restart stops claiming an exited session is idle -- walked the whole file a second time, after `Transcript::open` had just walked it for the sequence number. Both answers are wanted at the same moment by the same caller, so the cost was paid per session at exactly the point a restart is trying to be quick. `Transcript::open` now finds both in its one pass and reports the status it saw. The free function goes; a transcript knowing what it last recorded is where that belongs anyway.
