/**
 * Regression tests for issue #844: manifest version sync.
 *
 * Verifies that `scripts/sync-manifest-versions.cjs` correctly stamps the
 * package.json version into every registered runtime-integration manifest,
 * and that all currently-tracked manifests are in sync.
 *
 * Key deliverable: the regression guard (test d) asserts that any committed
 * JSON file with a top-level `version` field matching package.json is
 * registered in VERSIONED_MANIFESTS — forcing explicit opt-in for future
 * manifests.
