/**
 * Exercises host-injected extension kit APIs during setup.
 *
 * Use when:
 * - Verifying that an extension can consume injected kit APIs
 * - Testing end-to-end extension host bindings from a real extension entrypoint
 *
 * Expects:
 * - The host exposes `kit.widget.test` to the extension runtime
 * - The manifest grants the extension permission to use the kit
 *
 * Returns:
 * - Resolves after persisting the observed host state into a dynamic binding config
