"""Detached gated build: run the full CLI build and record the verdict.

Spawned by revise.py's fast path so customers see previews in seconds while
STEP/STL/gates grind in the background. Verdict lands in jobs.json under
"concept-<name>" (triage lists failures; a failure also reopens a note on the
design so it surfaces on the studio page).
