Genesis: dev-only artifact catalog at /catalog

A visual inventory of everything the simulation can draw, rendered by
the real factories at x3 with hard pixels: 15 structure roles (with
GENERIC tags on the 7 that share plain-house art) + progress ladder +
roof styles + a night toggle, 7 tree kinds x 4 seeds with felling and
stumps, all 58 prop pool sprites, animated inhabitants (bot actions,
cart, crane, mill wheel; frozen under reduced motion), bridge stages,
road strips, biome swatches, the 18 accents, and a coverage-notes
section that is the workbench to-do list for growing the catalog.

Dev-only by construction: getStaticPaths returns no paths in prod, and
the island mounts inside an import.meta.env.DEV branch so not even an
orphan JS chunk ships — the public build is still exactly 7 pages.
Additive exports only (paintRoad extracted from renderGenesis with
identical output; makePools/strip/drawBridge/gen tables exported).
