The chat opens the sessions drawer with a left-edge swipe and the
workspace drawer with a right-edge one, but neither could be closed the
same way: the only way back was the header X or the Android back button.
Reuse the edge-swipe hook on both open drawers so the mirrored gesture
closes them. To keep that free of the row swipe actions in the sessions
list, those are mirrored too: session, project and worktree rows now
reveal their actions on the LEFT with a swipe to the right, in the
mirrored button order so a partial drag still exposes delete first. When
a row has its actions out, the closing swipe puts them away first
instead of closing the drawer.
The hook grew an `enabled` flag so the listeners re-attach when a drawer
opens or a tablet rotates the workspace between panel and drawer.
Testing: package type-check and lint; gestures need a device check.
