Reactive current-user identity. Returns null until the first native
currentUser() read completes (lazily primed on mount), then re-renders
on every IDENTITY_CHANGED native event (e.g. after identify() or
logOut()). Reads are synchronous off the local store after that first
fetch — no network call on every render.
