Summary

Adds Prev/Next navigation buttons and n/p keyboard shortcuts to jump between changes in diff mode, with amber outline highlighting the current change and an "X / N" counter
Persists diff state via ?compare=<version> URL parameter — diffs survive page reloads and link navigation within the docs
Intercepts in-doc link clicks during diff mode to carry the compare parameter forward automatically

Closes #58, closes #59

Test plan

Enter diff mode, verify "N changes found" count appears in the banner
Click Prev/Next buttons — scrolls to each change with amber outline highlight
Press n/p keys — same navigation behavior (verify no conflict when focused on search input)
Enter diff mode, check URL has ?compare=X, reload page — diff re-engages automatically
Click a doc link while in diff mode — new page loads with diff still active
Exit diff mode — ?compare= removed from URL
Switch version (not compare) — diff mode not carried over
Page with no changes — "no changes on this page" shown, nav buttons hidden
Invalid ?compare= value in URL — silently ignored, no diff triggered

Adds prev/next navigation buttons and keyboard shortcuts (n/p) to jump
between changes in diff mode, with an amber outline highlighting the
current change. Persists diff state via ?compare= URL parameter so
diffs survive page navigation and reloads. Intercepts in-doc link
clicks during diff mode to carry the compare parameter forward.

Closes #58, closes #59
