issue: #45847
After a collection is successfully loaded, the shard-leader state on the
QC may still not be marked as serviceable. It becomes serviceable only
after the scheduled distribution update runs, which will also invalidate
the shard-leader cache on the proxy. Therefore, even if queries are
already executable, the shard-leader mapping on the proxy may still
change afterward.
Try to ensure—as much as possible—that the proxy’s shard-leader cache
remains stable before killing the mixcoord.
