- Add MCR_REGISTRY constant, is_mcr / mcr_repo / fetch_mcr_tags helpers mirroring the Docker Hub and GHCR pattern. Tags are fetched via the Docker Registry V2 API with RFC 5988 Link-header pagination (anonymous access; MCR is a public read mirror). Wire MCR into both the external test_image_versions warning surface and the find_outdated_updates orchestrator in utils.update.docker. - Bump mcr.microsoft.com/playwright in test-e2e-playwright from v1.59.1-noble to v1.60.0-noble — the update was surfaced by the new MCR detection path.
