fix: wire ignoreAntialiasing to pixelmatch AA forgiveness toggle

[wswebcreation]

In v10 the pixelmatch engine always ran with anti-aliasing forgiveness enabled, even when ignoreAntialiasing was false. The option had no effect on comparison behaviour.

What changed

• ignoreAntialiasing now toggles pixelmatch's AA handling: true forgives anti-aliased pixels, false counts them as mismatches.
• The default is now ignoreAntialiasing: true, matching the forgiving pixelmatch behaviour users already get in v10.
• ignoreLess and ignoreNothing keep their own threshold behaviour; AA forgiveness is controlled independently via ignoreAntialiasing.

Migration

• No action needed if you rely on the current forgiving defaults, comparison behaviour stays the same.
• If you explicitly set ignoreAntialiasing: true today, that remains redundant but harmless.
• Set ignoreAntialiasing: false when you need strict comparison where anti-aliased pixels count as differences.
