 * Walk a hydrated step's `items` tree and collect every leaf

 * groups are excluded (they're tested separately and have their own item
 * shapes that don't fit `HydratedElement`).
 *
 * Used by `hydrateStep.*.test.ts` files to assert which fields a step
 * surfaces — the tests typically map this output to `.key` and check
 * inclusion of a few expected keys.
