/**
 * Authentication plugin that initializes auth state on app mount (client-side only).
 *
 * This plugin automatically:
 * - Restores the user session from Pocketbase's authStore on page load
 * - Sets up cross-tab synchronization via Pocketbase's onChange listener
 * - Enables session persistence across page refreshes
 *
 * **Lifecycle**: Runs once on app mount, before any pages are rendered.
 *
 * **Cross-Tab Sync**: When a user logs in or out in one browser tab, all other tabs
 * automatically update their auth state within ~2 seconds (handled by Pocketbase SDK).
 *
 * **Session Restoration**: On page refresh, the plugin checks Pocketbase's authStore
 * and restores the user object if a valid session exists.
 *
 * @see {@link useAuth} for the auth composable API
