Subject: [PATCH] feat(desktop): marquee clipped inline row titles on hover
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The one-line session row gets the exact treatment the inbox card's title
already has: hovering a truncated title glides the clipped tail into view —
one direction at constant speed, a short hold at each end, then a snap back.
Same armMarquee/disarmMarquee handlers, same CSS, so overflow is measured on
pointerenter, short titles never move, hover state lives in DOM attributes
(no re-render of the memoized row), and reduced motion disables it.
