Emits a rename as one ->rename(~old, ~'new') per mapping, chained in
mapping order: the engine's array form fails (PLAN ยง8.8). No mapping names
another's column, so the order doesn't matter. Names travel as JSON
strings, so any valid name needs no quoting. The emitter checks the names
come out as the node's inferred schema, so a mismatch fails in Cube, not on
the engine.
