Subject: [PATCH] ci(mcp-server): lowercase the GHCR image tag (repository name
 must be lowercase)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The image job tagged ghcr.io/${{ github.repository }}/agentkeys-mcp-server, but github.repository keeps the repo's real casing (litentry/agentKeys — capital K), so docker buildx rejected it: 'invalid tag ... repository name must be lowercase'. The job runs only on push to main (skips on PRs), so it first failed on the #149 merge (Actions run 26719167517).

Fix: a 'Resolve lowercase image name' step lowercases $GITHUB_REPOSITORY via tr (portable to bash 3.2 per CLAUDE.md, not the bash-4 ${,,}) → ghcr.io/litentry/agentkeys/agentkeys-mcp-server, fed to both :latest and :$sha tags. YAML validated; tr output verified locally.
