+- **BREAKING:** Remove `getHeadlessAllProvidersMinimumVersion`; app-version
+  gating for `moneyHeadlessAllProviders` is owned by the LaunchDarkly
+  `versions` wrapper (processed by `RemoteFeatureFlagController`), not a
+  payload `minimumVersion` field. `featureVersion` fail-closed enablement and
