GitDiffModel class

A git diff viewer bubble.

Parses unified diff text and renders it with syntax highlighting, line numbers, and scrollable navigation via an embedded ViewportModel.

Example

final diff = GitDiffModel(width: 80, height: 24);
final loaded = diff.setDiff(rawDiffString);

// In update:
final (newDiff, cmd) = loaded.update(msg);

// In view:
print(loaded.view());
