Merge Risk: 🟡 Moderate · up to The new responsive max-width API works for the primary widget/window-body case, but on macOS a widget with a max-width cap can silently lose its cap-and-center behavior when it is also used as a window's content view, a sheet body, a tooltip's content, or a lazy-list/table row or cell, because those paths still fetch the unwrapped inner view instead of the capped layout wrapper. This should be fixed before merge to avoid inconsistent behavior when the new API is combined with these other macOS widgets. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Preserve the MaxWidthView wrapper when attaching widget views.
When widgetSetMaxWidth is applied, get_widget returns the inner content view. The sheet body, rich-tooltip content, and lazy-vstack/table row callbacks then pass that view to setContentView, addSubview, or AppKit row hosting. AppKit moves the content out of its MaxWidthView, leaving the wrapper registered without its content and disabling the cap and centering. Use get_layout_widget for these inserted views. Keep rich-tooltip host lookups on get_widget.

Adds
widgetSetMaxWidth(widget, maxWidth)for responsive content columns: fill the available width below the cap, then remain centered at the cap as the window grows. Padding stays inside the capped width.macOS uses an Auto Layout container to preserve each stack's alignment and the original widget's styling, including when the cap is applied after insertion. JavaScript and WebAssembly targets use CSS max-width and automatic side margins. Other backends accept a documented no-op, as permitted by the issue. Includes TypeScript declarations, the platform support matrix, and a usage example.
Fixes #10167.
