* fix(app): keep one hover card open while scanning sidebar workspaces
Sweeping the pointer down the workspace list showed cards about three
frames late, stacked two or three at once, and left some open after the
pointer moved on.
The card was positioned through an async chain (measureInWindow, then
onLayout, then a position effect, then the portal's passive mount), so it
painted at -9999 first. While unplaced, its safe-zone bridge covered
everything above the trigger, so upward pointer moves kept cancelling its
close timer. The previous card also stayed for the close grace period
plus its fade while the next one opened.
Now each overlay layer holds one open card, and opening another trigger
closes it immediately. The card reads its trigger and overlay rects in a
layout effect inside the portal, so the first painted frame is already
placed. The grace timer still covers jitter and the gap onto the card.
* test(app): name the hover scan workspaces so the resting row's card is identified
