native/src/test-setup.ts

// Vitest setup. Two pieces of plumbing the unit tests need:
//
// 1. AsyncStorage: the Zustand `persist` middleware used by several stores
//    reaches in during `set()` calls, which on a `node` environment crashes
//    inside the RN AsyncStorage shim (no `window` global). Swap in an
//    in-memory implementation.
// 2. react-native: the bundled entry point is Flow-typed and rolldown can't
//    parse it. Stub the few surfaces used at module-load time so any store
//    that transitively imports `react-native` (via push / client-cert
//    bridges) loads cleanly. Tests that actually exercise native modules
//    re-mock the relevant module locally.
