/*
 * list_notifications.c — list the authenticated account's notifications
 * (app.bsky.notification.listNotifications).
 *
 * Demonstrates:
 *   1. High-level agent login with wf_agent
 *   2. Fetching notifications via the typed wrapper
 *      wf_agent_list_notifications_typed
 *   3. Printing each notification's reason, author, and (optional) text from
 *      the owned record subtree.
 *
 * Usage:
 *   list_notifications <service-url> <handle> <password> [limit]
 *
 * [limit] is the maximum number of notifications to fetch (defaults to 50).
