Adds Docker Hub as the secondary OCI registry while keeping GHCR primary.

Changes:

  • publish the same multi-platform build to GHCR and Docker Hub
  • use vars.DOCKERHUB_USERNAME and secrets.DOCKERHUB_TOKEN
  • exact-digest qualify both registry references
  • keyless Cosign sign and verify both registry references
  • extend post-release audit to require GHCR/Docker Hub digest parity and platform coverage
  • document the dual-registry release model

Existing releases, including v0.2.0, are not changed.
