Subject: [PATCH] Session: add a persistent chrome-toggle handle at top center

Three-finger tap still works as a power-user shortcut, but now there's a
small glass chevron pill at the top center that flips between chevron.up
(hide toolbar) and chevron.down (show toolbar) based on chrome state.
Discoverable and reachable from one hand.
