fix(intro): make intro explicitly stateful

Instead of randomly disappearing because some random event might have
caused mid_start or bot_scroll_start to randomly take a low value, treat
intro message as a _first class stateful_ thing.

This means that intro message will kept being _redrawn_ as long as we
are in the state it should be shown. This also includes screen resizes.
you will not lose the intro message because there was a delay in
detecting terminal features.
