mapper: cap concurrent map sessions per node
...
A node chose how many map streams it held, each pinning a session.
The fifth replaces the oldest; same shape as #3468 's mapper commit.

change: coalesce policy recomputes that carry an origin node
...
The recompute render ignores the origin and always carries the node's
own entry, so a burst of tag writes cost every node one per write.
