repo: move the wall to the object-store scan, pin the e2e workflow

minspec/.github#10 pins the content surface to every tracked blob,
read from the object store, bytewise, symlinks never followed. Point
the wall step at that merge. The e2e job called the reusable workflow
in workbench at the mutable `dev`; pin it to the current dev commit.
