v159 emergency safety lock

Default behavior is locked. This build snapshots DefaultCacheBehavior before generating media behavior changes, restores it from the snapshot before upload, and refuses to update CloudFront if the Default behavior changes.

The app may update ordered CacheBehavior media rules only. It must not change Default response headers policy, CloudFront Function associations, or Lambda@Edge associations.
