Apple container: architecture map

apple/container runs Linux containers as lightweight VMs on Apple silicon Macs: the `container` CLI, the `container-apiserver` launchd agent and plugin helpers, all built on apple/containerization. This L0 is a system context: the shipped system, its build tooling and agent skill, and the macOS platform and external services it relies on. Container-grade with 1 drill-down (`sources`).
