Generate a unique color for index i using golden-angle hue distribution.
Produces unlimited perceptually distinct colors:
Hue: golden angle spacing (maximally distributed for any N)
Saturation: alternates between 65% and 80% to add variety
Lightness: cycles through 3 levels (45%, 55%, 35%) for depth
Colors are visually distinct for typical N. The hue uses golden-angle
spacing to stay maximally separated, but exact-hex collisions are
possible beyond ~1.8k distinct values (the first occurs at i=1842,
which matches i=12) because the output is quantized to 6-digit hex.
