The activity run, edit run, and sub-agent run cards now render through the
shared ClideCollapserCard primitive instead of ClideHolderCard. The
collapsed ticker now leads with the card label, the count sits in a
fixed-width slot, and the status tick is pinned to the right edge.
ClideHolderCard (T-266) is fully superseded — removed along with its test
and golden; the deeper-control-passthrough coverage moved to the
ClideCollapserCard widget test.
