/**
 * Async Job Polling example for unsandbox JavaScript SDK
 *
 * Demonstrates fire-and-forget execution with manual job polling.
 * Shows how to start an async job and poll for its completion.
 *
 * To run:
 *   export UNSANDBOX_PUBLIC_KEY="your-public-key"
 *   export UNSANDBOX_SECRET_KEY="your-secret-key"
 *   node async_job_polling.js
 *
 * Expected output:
 *   Starting async job...
 *   Job ID: job_abc123
 *   Polling for completion...
 *   Poll 1: status = running
 *   Poll 2: status = completed
 *   Final result: 42
