Single-pin sync of the drift-check meta-tooling to the corviduo-project-
template canonical (23271287 → 2659a17a). Consumer copy is byte-exact;
pin hash + pinned_at bumped. No runtime effect (meta-tooling, not product
code) → no version bump per SemVer skip-rule. The two tolerate_drift
worldtree prose pins (conversation-api-spec, affect-egress-consumer-
reference) are deliberately left STALE — their re-vendor is coordinated
with the R34/R35 eval's diff-review, not a blind sync.
