PlinthVisuallyHidden class

Renders child so screen readers announce it while sighted users never see it, matching Mantine's VisuallyHidden.

The common case is supplementary context for an icon-only control — e.g. an icon button whose visual meaning is obvious to sighted users but needs a text label for accessibility:

PlinthActionIcon(
  icon: Row(
    mainAxisSize: MainAxisSize.min,
    children: [
      const Icon(Icons.close),
      PlinthVisuallyHidden(child: Text('Close dialog')),
    ],
  ),
  onPressed: _close,
)

Uses the standard "clip to a near-zero size" technique rather than Opacity or Visibility.invisible — those keep the content fully in the layout and paintable (just transparent or skipped), which some screen readers still treat as hidden from them too. child stays in the semantics tree (Flutter includes it by default — nothing extra needed for that); only its painted/laid-out size collapses.
