CardMenu's pair-hover check read the popup's HoverHandler, which lives on
the background and never fires over a row: the rows' MouseAreas take the
hover events, so the panel only counted as hovered on its 5px padding.
Crossing from that padding into the child's first row read as "left both
menus" and the 350 ms leave timer closed the pair — the Copy submenu
closed the whole context menu as soon as it was entered.
A menu is now hovered while its panel OR one of its rows is (one hot row
at a time, held by reference so a destroyed row cannot leave it stuck),
and the pair check reads that on both menus. scripts/test-card-menu-qml.sh
drives the pointer through the parent row, the child's rows, back to a
plain row and out, and joins the runtime gate and CI.
