- Add Dockerfile.containerd: multi-stage build that compiles MCP binary, assembles rootfs, creates Docker image tar, and bundles it with containerd - Add containerd-entrypoint.sh: auto-imports MCP image on first start - Fix MCP image reference: rename busybox_image to image in config, use fully-qualified docker.io/library/memoh-mcp:latest everywhere - Make image ref configurable via config.toml instead of hardcoded - Simplify deploy.sh: remove manual nerdctl/containerd-install steps
