/**
 * `agentsmarket webhook register <url> --events=<csv>` — register a webhook
 * URL for skill invocation lifecycle events (vertical wedge).
 *
 * Flow:
 *   1. Verify logged in (loadConfig); hint exit if not.
 *   2. Parse + validate URL (https://, ≤ 2048 chars).
 *   3. Parse --events (comma-separated). Allowed (mirrors the server's
 *      KNOWN_WEBHOOK_EVENTS):
 *        - invocation.completed
 *        - settling.created
 *        - settling.settled
 *   4. POST /v1/webhooks with auth headers + body.
 *      Server returns the webhook row + secret (returned ONCE).
 *   5. Save the webhook (id, url, events, secret) to local config so users
 *      can re-verify deliveries offline.
 *      File: ~/.config/agentsmarket/webhooks.json (mode 0600).
 *   6. Print success summary with the secret prominently displayed.
 *
 * File layout (webhooks.json):
 *   {
 *     "webhooks": [
 *       {
 *         "id": "hook_...",
 *         "url": "https://example.com/hook",
 *         "events": ["invocation.completed"],
 *         "secret": "64 hex chars",
 *         "registered_at": "2026-09-25T12:00:00.000Z"
 *       }
 *     ]
 *   }
 *
 * Notes:
 *   - The server returns the secret only once; subsequent GETs omit it.
 *   - To rotate: register a new webhook + DELETE the old one
 *     (`agentsmarket webhook delete <id>` — not yet implemented).
