/**
 * Expo hook for OAuth sign-in and identity linking.
 *
 * Opens the Sublay-brokered provider consent screen in the system browser via
 * `expo-web-browser` and receives the result through a custom-scheme deep link.
 * API-compatible with the web `@sublay/react-js` hook, with two mobile deltas:
 *   - `redirectAfterAuth` is REQUIRED (there is no `window.location` default).
 *   - `handleOAuthCallback` is a no-op shim returning `false` — the redirect is
 *     resolved inline by `openAuthSessionAsync`, not on a separate callback page.
 *
 * Token persistence is automatic: the dispatched tokens are picked up by the
 * `AccountManager` (via `useAccountSync`) and written to SecureStore.
 *
 * Usage (sign-in):
 *   const { initiateOAuth } = useOAuthSignIn();
 *   await initiateOAuth({ provider: "google", redirectAfterAuth: "myapp://auth/callback" });
 *
 * Usage (link provider to current user):
 *   const { linkOAuthProvider } = useOAuthSignIn();
 *   await linkOAuthProvider({ provider: "github", redirectAfterAuth: "myapp://settings" });
