run_tests.sh: tag-drift is now a non-blocking WARNING in SUMMARY.

Hard-blocking the bundle on a heuristic grep of PHASE_HISTORY.md prose was
fragile and created override pressure (invisible bypass -> dead-weight check).
Now: scope grep to 'tag `PHASE_X_END`' declarations (not prose mentions),
and report drift as a warning recorded in SUMMARY (travels in reviewer.zip),
without blocking. Drift stays visible; the bundle always builds.
