Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds selectable search scopes and a new split-header presentation; localized styling issues could cause inconsistent header surfaces or collapsed labels in constrained layouts.

Pull request overview
This PR extends limel-code-diff’s in-diff search from being limited to removed lines to a user-selectable scope (removed, added, or changed), with a compact scope picker embedded in the search bar. It also adjusts default behavior and visibility so search is available whenever there is any diff.
Changes:
- Added
SearchScopeplus pure helperspickDefaultScopeandlineMatchesScope(with unit tests) to support scoped searching. - Updated
limel-code-diffto tracksearchScope, render a<limel-button-group>scope picker, and apply highlighting/counting only to lines within the active scope. - Updated all locales to generalize the search label and add new scope-related translation keys.

src/components/code-diff/code-diff.tsx:402
- The PR description focuses on search-scope changes, but this hunk also changes the split-layout header by moving the old/new labels into a new
.diff-header__column-labelsrow. If this UI change is intentional, it should be called out in the PR summary (or moved to a separate PR) to avoid surprising reviewers and consumers.
isSplit && (
// In split mode the labels live in their own row below the
// actions toolbar, mirroring the 4-cell layout of `.diff-line--split`
// so each label sits above the column it describes.
<div class="diff-header__column-labels">
src/components/code-diff/code-diff.scss:128
- In split layout, the header (
.diff-header) already has a bottom border, and the new.diff-header__column-labelsrow also addsborder-bottom, which will result in two horizontal divider lines (one between the toolbar and labels, and one below the labels). If the intent is a single divider below the labels, consider removing the header border only in split mode.
.diff-header__column-labels {
display: flex;
align-items: stretch;
border-bottom: 1px solid var(--diff-border-color);
