Module code_diff 

Code diff viewer: a unified patch as reviewable hunks.

Agents propose edits; people review them. CodeDiff shows one file’s patch with old/new line gutters, change tints, a copyable source, and, when reviewable, an Accept / Reject pair per hunk that reports CodeDiffEvents by file path and hunk index. DiffFile::from_unified parses standard unified diffs so the application can hand over what a tool already produced.

The code itself is rendered through the upstream syntax-highlighted, selectable text view; the gutter and change tints are laid out beside it on the same rem-based line height so numbers and lines stay aligned.
