This PR turns the engine into a read-only reviewer of a dirty worktree: combined diff acquisition with rename detection, side-by-side row alignment with collapsed context gaps, word-diff spans, tree-sitter highlighting, frame rendering, and the event loop with file navigation. An inline layout is available behind a runtime toggle.
The renderer ports the spike's modules; one latent span-precedence bug in the port (first-match lookup dropping word emphasis) is fixed here and pinned by a render test.
