Handle Currents "Cloud Run Finished" table rows where the trailing
"s" in long duration values wraps onto its own continuation line.
Instead of appending that standalone continuation to the end of the
host row, drop the wrapped row and rely on the existing duration
parser to accept values without the trailing "s". This preserves all
host rows in parent summary parsing for completed non-categorized runs.
Also record the failure mode and recovery guidance in the ATVM run
learnings doc.
