Approximately what mass ratio defines the boundary used to distinguish high-mass stars from low-to-intermediate mass stars regarding final evolution?

Answer

8 times the mass of the Sun ($8 M_{\odot}$)

The evolutionary path diverges sharply based on initial mass, with stars significantly more massive than about 8 times the mass of the Sun following the high-mass track.
