The ray trace approach was designed focusing mainly on Oklab/OkLCh. Further evaluation shows that some spaces twist a little different through the RGB spaces and can yield results not as good, CIELCh being an example.
Adjust the algorithm so that if a point is found along the reduction path below the gamut surface, that point becomes the new anchor.
This generally tightness the range in a few passes and prevent some spaces from having larger than expected hue or lightness deviations.
