The image was built and saved as an OCI archive (via buildah push oci-archive:...) but trivy was invoked with --input which only accepts Docker-format tars. Switch to the oci-archive: image reference so trivy correctly parses the OCI layout. Also add a GitHub Actions cache step for ~/.cache/trivy so the 85 MiB vulnerability DB is not re-downloaded on every release run. https://claude.ai/code/session_01FovhL9GqcEehmbUDtPyt5Z

Summary
This PR improves the Trivy vulnerability scanning step in the release workflow by adding caching for the vulnerability database and updating the image input format to use OCI archive syntax.
Key Changes
~/.cache/trivyto avoid re-downloading the vulnerability database on every workflow run, reducing scan time and improving efficiency--inputflag to theoci-archive:URI scheme for specifying the container image source--inputflag and restructured the command to use the modern OCI archive formatImplementation Details
runner.osandgithub.run_idto ensure proper cache isolation per OS and workflow runoci-archive:build/${IMAGE_NAME}.tar) is the recommended approach for scanning local container images with Trivyhttps://claude.ai/code/session_01FovhL9GqcEehmbUDtPyt5Z
