A run inferred "still working" from a missing result alone, so a call
left unresolved — by an interrupted turn, or an agent that moved on —
pinned its run as live forever. That stranded the summary in the present
tense ("Exploring 2 files" on a finished turn) and, because a live run
withholds its toggle so approvals can't hide, left the run permanently
expanded with no way to collapse it.
Qualify liveness the way ToolEntry already qualifies a row's: a missing
result only means pending while the run is the tail of a running
message. Liveness is now passed into summarizeToolRun rather than read
off the calls, since it isn't a property of the calls.
