The diff viewer never soft-wrapped, so a long changed line ran off the right edge. Diff panes now follow Settings › Editor › General › Soft-wrap files for the file, and the viewer's settings menu has a Use Soft Wraps checkbox that overrides it for all diffs and is remembered with the other viewer options. View › Active Editor › Soft-Wrap (editor.toggleSoftWrap) also toggles it when a diff pane has focus. Toggling reconfigures both panes in place, keeping the selection and the scroll position, including aligned split diffs.
Closes#2263

Blocks that were moved unchanged, re-indented or moved and then edited are paired across the split diff: each side gets a link to the other (keyboard accessible), moved lines carry a left accent bar, edits inside a moved block get word-level highlights, and the toolbar counts moved blocks and whitespace-only changes. Staging and reverting still work on the original hunks.

* feat(vcs): IDEA's diff algorithm and change colouring in the diff viewer
Port IntelliJ's text comparison to TypeScript (src/features/vcs/comparison):
Myers/patience LCS with unique-element discarding, ByLine (smart matching
that skips unimportant lines, chunk optimizer, second-step correction),
ByWord (word chunks, punctuation matching, whitespace policies, line block
splitting) and ComparisonManager's compareLinesInner / processBlocks. The
port runs IntelliJ's own LineComparisonUtilTest, WordComparisonUtilTest and
SplitComparisonUtilTest cases (459 runs), converted to ideaCases.json.
MergeView chunks now come straight from these line fragments, with the
inner word fragments as chunk changes, instead of @codemirror/merge's
presentable diff. Revert and >> / << replace lines as
DiffUtil.applyModification does.
Colour changes as IDEA does: modified (blue), inserted (green) and deleted
(grey) by chunk type, a lighter line background for chunks whose words were
compared, each word fragment in its own type at full line height, a thin
bar for a fragment empty on one side, and the colours carried into the
gutters and the divider bands. New --diff-modified / --diff-inserted /
--diff-deleted theme tokens, imported from .icls DIFF_* attributes.
Add a Playwright suite over a generated git repository of diff cases,
including 10,000-line files, in every viewer mode.
