/**
 * HostFacade types.
 *
 * The HostFacade is the central type that bridges a host application with
 * an embedded product via the transport layer. It exposes handler
 * registration methods for every protocol method, translating between
 * the versioned wire format (v1 tagged enums) and plain TypeScript types.
 *
 * Handler param/ok/err types are derived from the SCALE codec definitions
 * in `hostApiProtocol` via `RequestParams`, `ResponseOk`, `ResponseErr`,
 * `SubscriptionParams`, and `SubscriptionPayload`.
