* fix(macos): defer isOverflowing mutation to break SwiftUI render loop

measuredHeight() mutated model.isOverflowing synchronously during a SwiftUI
view update cycle. The onChange(of: attributed) handler triggered
updateWindowFrame → targetFrame → measuredHeight, which set isOverflowing,
invalidating the view and re-triggering onChange — an infinite render loop
causing 100% CPU pinwheel.

Fix: defer the isOverflowing mutation via DispatchQueue.main.async with an
equality guard to prevent redundant updates. The frame calculation itself
remains synchronous so the window size is correct immediately.

Fixes #43480

* fix(macos): preserve latest overflow measurement
