Async job polling example - demonstrates fire-and-forget execution

This example shows how to:
1. Start jobs asynchronously with execute_async()
2. Poll job status with get_job()
3. Wait for completion with wait_for_job()
4. Cancel jobs with cancel_job()

Usage:
    python async_job_polling.py

Or with custom credentials:
    UNSANDBOX_PUBLIC_KEY=... UNSANDBOX_SECRET_KEY=... python async_job_polling.py
