Detailed Description

Instruction linking a source color to a reference color in another palette.

An IndirectLink says: "source_color in palette source_palette should occupy the same slot as ref_color in palette ref_palette." During palette construction, this translates to setting source_color's position to IndirectPosition{ref_palette, ref_color}. When resolved, both colors end up at the same slot index in their respective palettes, enabling tile sharing.

Invariant: source_palette != ref_palette (links always cross palette boundaries)
