Package impl is the v1 implementation of the IBC host logic for the gno.land/r/onbloc/ibc/union/core proxy. The proxy keeps the stable identity (admin, package address), the Store, and the app registry; this realm holds the swappable protocol logic and is injected with the proxy-owned store (core.IStore) at install time.
core/v1 implements the client, connection, channel, packet, app registry, and query surfaces behind the proxy's ICore interface.
New constructs a fresh v1 impl. The store is injected by the proxy at install time via SetStore, so it is nil until installed.
