Module diff 

Line diffs of two texts, git style, for crate::widgets::DiffView: added and removed lines with their old and new line numbers, grouped into hunks with a few unchanged lines of context around each change; the unchanged runs between hunks fold away.

Diff::json compares two JSON documents by key instead of by text: both are printed with sorted keys first, so reordered keys are not noise, and a long array (cells, tiles, labels) prints as one line, so a changed array reads as one summary line (cells: 2,539 → 2,712) instead of thousands of numbers.

Plain data: no UI here, so an app (or its tests) can compute a diff without a window.
