Run and read a JavaScript Code node

When the payload is deeply nested, mapping fields one by one gets tedious. A JavaScript Code node can reshape everything in one pass and add computed fields like a fetch timestamp.

Import the starter, run it, and compare the Code node's Input and Output to see how the pinned Stockholm data becomes flat fields — this exercise is about reading the transform, not writing it.
