Collects every projection in a Flake into an alias-keyed index.
Each binding alias, unique within a projection (qest §5.6), maps to the single flake bearing it. A union-typed
binding folds its variants into that flake's entries rather than fanning them to
sibling alias-bearing flakes, so no alias is ever shared.
