Kelvin Amoaba cc1e3740da feat(computer-use): scroll and select list rows in background Linux windows, and aim GTK 4 clicks (#42201)
* feat(computer-use): scroll and select rows in background Linux windows, and aim GTK 4 pointer input

Scroll moves the nearest scroll bar's value by whole viewports, handing
the scroll outward at a view's end, or pages a web document with
Component.ScrollTo, before falling back to the pointer. A click on a
list row with no action selects it through the list's Selection when
the index is proven to name that row. GTK 4 rectangles come from
WINDOW extents plus the X11 client origin, since its SCREEN extents
read [0, 0, w, h].

* fix(computer-use): keep Linux background scroll and select honest under partial and slow results

Wait for ScrollTo to move before planning the next page, report pages
already scrolled instead of falling back, let refused scroll bars fall
through, clear a multi-select list before a plain-click select, accept
only an InvalidArgs refusal as index proof, bound child walks, and
read GTK 4 origins lazily.

* fix(computer-use): scroll the innermost Linux view that overflows, and bound the scroll search

ScrollTo now runs on each ancestor that overflows its own box, innermost
first, so an inner scroller moves before the page; coordinate scrolls
start from the deepest node under the point. Cap the scroll bar search
to small containers, report a document at its end as a no-op, keep
looking past an unusable spanning child, and look up GTK 4 window names
once per operation.
