MakerOf picked the first product for a design from any maker, the same
tie-break Brand() uses to resolve a runtime item's actual attribution.
That made census silently agree with an attribution it has no business
asserting on its own. Census's job is to report what the catalog says,
including when a design has more than one seller.
MakerOf now lists every distinct maker that sells a design (via its
products, manufacturer set), in record-key order, or "(none)" when no
product sells it. The existing duplicate (maker, design) detector is
unchanged. Verified byte-identical `census` output before and after,
since today's catalog has no design with two makers.
