/**
 * The production wiring (PluginHostDepsFactory) that connects a plugin's
 * capability host to the real privileged modules (#plugins, M1). Verifies the
 * per-plugin data db is cached, a granted db:own call works through the wired
 * host, and trip broadcasts are force-namespaced to plugin:{id}:{event}.

 * packing/day-notes/days/assignments/oauth/llm-config/files/collab/vacay/
 * permissions/trips/places/collections/atlas/notifications)
 * are constructor-injected stubs; legacy services/* domains stay path-mocked
