Handle getUser rejection in onAuthStateChange

[max-bader]

What

In onAuthStateChange, the initial auth.getUser() call had no rejection handler. This adds a .catch() so a failed lookup notifies the listener with SIGNED_OUT / null instead of surfacing an unhandled promise rejection.

auth
  .getUser()
  .then(({ data }) =>
    callback(data.user ? "SIGNED_IN" : "SIGNED_OUT", data.user),
  )
  .catch(() => callback("SIGNED_OUT", null));

Testing

• bun test — 18 pass, 0 fail
