create_catalog_item
Add a furniture or structural piece the catalog does not have (a staircase, bunk bed, sofa, kitchen island) so it can be placed like any other item. Give real-world dimensions in inches at rotation 0: width_in along x, depth_in along z, height_in up. category is a lowercase slug (stairs, sofa). support: floor (default), wall (needs mount_height_in), or surface (rests on another item). Returns catalog_id for place_item. The engine then enforces its footprint, support and clearances exactly like a seeded item.
