posix.sh::finish and windows.ps1's finally write the result (finished_at =
now) BEFORE the R6 release wait, which lasts up to 7200 s while a survivor
holds the checkout lock, and before the relaunch. The relaunched Desktop has
no expected run id and handoff-result.ts drops a non-manual result older than
30 min, so a failure or warnings result was silently discarded after a long
wait.
The early write stays (a kill during the wait still leaves a result); when the
wait actually ran, the result is published again after it with the real
finish time, unless something already consumed it. The release records that
it waited (RELEASE_WAITED / $script:MarkerReleaseWaited).
Tests: posix live cell (RED at start: finished_at 3 s before the survivor
let go) and the Windows twin with a timed checkout-lock holder.
