Detailed Description

Position state for a color whose slot is determined by another color in another palette.

IndirectPosition says "my slot is wherever @c ref_color ends up in palette @c ref_pal_index." This is the key insight from borytiles by ishax-kos (https://github.com/ishax-kos/borytiles): by referencing colors rather than absolute slots, links remain valid even when sequential fill places non-shared colors at different positions than the base palettes. Corresponds to the Indirect(Palette_index,Color_index) variant of borytiles' Position_in_palette enum.

Indirect chains are resolved after sequential fill by following ref_pal_index / ref_color until hitting an AbsolutePosition. Cycle detection caps resolution at pal::num_pals iterations.
