Text diff + pixel-XOR visual diff · changes-only view

Side-by-side comparison with word- and line-level text diff plus a luminance-aware visual diff for layout changes that text alone misses.

diffWords / diffLines with custom token map so boundaries align cleanly.
visualDiff: pixel-XOR with blue (removed) / red (added) / grey (unchanged) overlay.
changesOnly() filter for review-only views.
