/**
 * Status dashboard runtime hook.
 *
 * Thin bridge that wires a {@link createNodeStatusClient} instance to a global
 * seam, `globalThis.SDN_NODE_STATUS`, which the design-built status dashboard UI
 * reads. This mirrors the `SDN_MANIFESTS` global registry pattern used by the
 * served apps: the runtime owns the data source, the design owns the rendering.
 *
 * Kept dependency-light on purpose so the `./ui` dist contract consumed by
 * OrbPro stays lean — it only pulls in the status client + view model.
