Function resourceCatalog

Builds both halves of a SceneResourceCatalog from one map of logical key → resource (§79, 2026-08-07).

const materials = resourceCatalog([
  ["materials/brick", brick],
  ["materials/glass", glass],
]);
const io = registerSceneNodeTypes({ materials, geometries });

One map rather than two functions because the two directions have to agree: a keyOf writing a key its get cannot resolve produces a document that saves cleanly and refuses to load, which is the failure this whole seam exists to make impossible.

A resource published under two keys keeps the first, in iteration order, so the document a scene writes does not depend on which alias the caller happened to look up — both keys still resolve, so nothing is lost.
