Original Pull Request: https://github.com/anomalyco/opencode/pull/13210

State: open
Merged: No

What does this PR do?

Adds a marquee scroll animation on hover to sidebar session titles, so that it is easier to read the session title without opening it. Long titles truncate with ellipsis by default and smoothly scroll to reveal full text on hover.

How did you verify your code works?

tested to ensure animation starts immediately on hover, and resets when mouse leaves the session item
made sure the speed is same for both long and short titles
made sure we only scroll if there is overflow
