Brandon ThomasandClaude Opus 5.5 ed181a809e Render: pictures with opposite corrections no longer share decoded pixels ...

The decoded-picture cache keyed adjustments with an xor-multiply mix in
which brightness b, contrast c and -b, -c collide (the sign bits cancel),
so of two copies of a picture, one +40% bright and contrast and one -40%,
both showed whichever was decoded first. The key is now a real hash.

Wild synthetic set: brightness/contrast grid 27.86 -> 15.93.
