+description: Download the utoo binary built from origin/next HEAD (by build-next-* jobs) into a temp directory and export $UTOO_NEXT_BIN. Used by bench-phases to add a `utoo-next` baseline column — the merged-but-not-published code — so PRs can show their delta vs the trunk baseline (not just vs the older npm-published version).
