Generalizes the huggingface-hub lockstep test (#72320) to the whole
LAZY_DEPS surface: any package exact-pinned in LAZY_DEPS that the core
lock also resolves must pin the SAME version, so hermes update's lazy
refresh can never churn or downgrade a shared package out from under
its other consumers (#60783 class, #31817 class).
Together with the anchor-based activation gate (previous commit,
salvaged from #27878 by @paralegalia), this closes both halves of
#44404: features no longer false-activate from shared transitives, and
even a feature that legitimately activates cannot move a shared package
away from the locked version.
