Engine part of viewer picking: replace / add / remove the top-coverage ID at a layer-space point in one undo step, at the time the Selection was read. The aux channels come from the render's own path (Renderer::layer_aux, shared with the effect host; footage at its source time, 3D precomps) through a renderer set up like Session::render (expressions, render prefs, layer cache). An optional scale snaps the point to the pixel a preview at that resolution samples. New effects::crypto_select quotes names and falls back to <hex> for unnamed, wildcard-looking or ambiguous names. effect.cryptomatteAt is the read-only hover query.
