David MannandClaude Opus 5.5 41d6490ef2 test(compose): CMYK reference keeps the source ink over nothing (#12079) ...

The reference's source-over computed s * sa / sa over an empty backdrop,
one ulp off the stored ink. Behind a Paint.NET Color Burn of a Posterize
that lands exactly on 73.5/255, the ulp flipped the 8-bit rounding and
random_documents_match_the_reference failed on main. Keep the source ink
when nothing shows through or both inks agree, as cmyk::normal does.
