jpmschweitzerandClaude Opus 4.8 1411e19ab4 ultrawide layout test coverage + shared setSurfaceSize helper (T-241)
Add setSurfaceSize(tester, width) to the widget harness — the reusable way to
test width-sensitive layout at an ultrawide surface (a wide SizedBox under the
default 800px surface is clamped, so the view's physicalSize must be set), the
foundation T-241 asked for.

Ultrawide cases on the surfaces most prone to width-proportional bugs (the T-239
class): ClideMarquee stays static when a line fits a 3440 slot (it was only
tested narrow); the quick-open palette stays width-capped, not stretched edge to
edge. The status bar already covers 600+3440 (T-239).
