A newly mounted navigator (the flow opening) dispatches its initial observer notifications during build; writing to a widget-bound ValueNotifier there throws markNeedsBuild-during-build. A microtask can't run mid-build and still lands before the next frame from a tap. Documents the pattern in the track-screens how-to and pins it with a widget test. Fixes #57
