volt: CHECK leg 4 reads HEAD's archive, not the worktree (Q142)

Browse Source 
Leg 4 built its copy from the worktree, so a dirty tree broke the leg that
exists to prove a copy grades itself. It now extracts wizard-work/quill from
HEAD with git archive; legs 2 and 3 remain the worktree readings, and the
script sets pipefail so a failed archive cannot read as an empty tarball.
