Get-LiveProcessCt caches a pid's creation time for the script's lifetime and
forgets it only when a probe SEES the pid dead. A delegate (the `hermes update`
child) that exits and whose pid is reused between two probes keeps the old
incarnation's time, so the release judged the unrelated new process live and
handed the marker to it (A7 rule 5), parking every later update behind it.
Every judgement made through New-MarkerContext (claim, delegate, heartbeat,
release) and the delegate line Add-MarkerDelegate writes now pass -Fresh,
which re-reads the time. Pollers that only ask "still alive?" (Wait-DesktopExit)
keep the cache.
Test (Windows live cell): a release with the delegate's pid cached at the
recorded ct but really owned by another incarnation deletes the marker instead
of handing it over. marker.sh reads /proc or ps on every call: no cache.
