/**
 * Fetch a Coolify application's runtime (container stdout/stderr) logs via the
 * Coolify REST API — no dashboard login needed.
 *
 * Usage (from the vibn-frontend/ directory):
 *   node scripts/fetch-app-logs.mjs <appUuid> [lines]
 *
 * The <appUuid> is the last path segment of the Coolify app URL, e.g.
 *   https://coolify.vibnai.com/project/.../application/hou4vy5mtyg5mrx3w4nl2lxv
 *                                                      ^^^^^^^^^^^^^^^^^^^^^^^^ appUuid
 *
 * Reads COOLIFY_URL + COOLIFY_API_TOKEN from vibn-frontend/.env.local.
 * Note: Coolify's /logs endpoint returns the *last N lines* of container output,
 * not a date range — pull a generous N and filter by date client-side if needed.
