/**
 * Hook that returns a function to atomically tear down the current WaaS session.
 *
 * Intended for integrations where the host app swaps the authenticated user within
 * a single tab (for example, when a product layers multiple identities on top of a
 * single Dynamic SDK instance). Calling the returned function:
 *
 *   1. Ends every active WaaS wallet-connector session, which triggers per-chain
 *      `dynamicWaasClient` cleanup and iframe ref-count decrement.
 *   2. Removes all Dynamic Wallet iframes (main + storage) from the DOM as a
 *      belt-and-suspenders step in case a consumer failed to decrement the ref count.
 *   3. Clears the persisted zustand store from localStorage so the next SDK load
 *      does not hydrate stale user/wallet state.
 *
 * After this resolves, the next `useExternalAuth`/auth flow starts from a clean
 * slate — new iframe, no cached keyshares, no stale store.
 *
 * Concurrent calls while a teardown is already in progress are ignored — the
 * callback is guarded by an in-flight flag so only one teardown runs at a time.
