• New ui.wrapLines config option (default true) and w keybinding to toggle line wrapping at runtime
• With wrapping off, delta is invoked with --wrap-max-lines=0 so full untruncated lines are emitted, and ←/→ pan the view (a quarter of the viewport width per press, from either panel since the file tree only binds h/l); trackpad horizontal scroll works too
• Side-by-side falls back to unified while wrapping is off, as delta truncates overflow in side-by-side mode; pressing s re-enables side-by-side and turns wrapping back on
• Wrapped/unwrapped renders are cached separately, and switching files resets the pan to column 0
• Footer diff stats no longer depend on the render-mode cache key, so they survive wrap/side-by-side toggles and theme changes (this was broken before for the s toggle as well)
• Ignore stale async delta renders that finish after navigating to another node or toggling wrap/side-by-side, instead of clobbering the visible content
