The fullscreen command needs to know whether the frame is narrow enough
that an expanded panel is fullscreen automatically. Reading it from a new
ctx.layout.viewportWidth widened the layout plugin's public face for this
one consumer. The seats already receive the frame width as owner props and
compute the rule they render with, so each seat now reports that verdict
through its inject face, as it reports its docking kit's room. The command
reads the latest report only when the user runs it, after the commit that
rendered the width has settled.
- Revert ctx.layout.viewportWidth and the test fakes that provided it.
- SidebarRightInjected gains reportAutoFullscreen.
