hub-frontend v1.19.35 is a hardened release with the signed image-hardening attestation (v1.19.34 was hardened before attestations existed). With it, every chart default with a hardening policy is an attested hardened release. Frontend runtime check and README updated. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
