Extends MCP to own the full build-push-deploy lifecycle. When deploying, the CLI checks whether each component's image tag exists in the registry and builds/pushes automatically if missing and build config is present. - Add Build, Push, ImageExists to runtime.Runtime interface (podman impl) - Add mcp build <service>[/<image>] command - Add [build] section to CLI config (workspace path) - Add path and [build.images] to service definitions - Wire auto-build into mcp deploy before agent RPC - Update ARCHITECTURE.md with runtime interface and deploy auto-build docs Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
