fix(ui): keep review diff text compact on iOS

[Waishnav]

ChatGPT iOS can apply WebKit text inflation inside the Pierre shadow-DOM diff renderer, making diff lines much larger than the surrounding card chrome. The diff canvas now uses a fixed 12px code size and explicitly opts out of automatic text inflation with text-size-adjust: 100%, while the rest of the card continues to follow host typography.

This also upgrades @pierre/diffs from 1.2.5 to 1.3.6 so the review UI is on the current renderer. The iOS host-specific visual path still needs confirmation in ChatGPT iOS because it cannot be reproduced by the local Linux build.

Fixed for this issue:

Twelve pixels keep each change near
