Approval workflow without a workflow engine — Python example.

Submit a purchase request with a multi-step approval chain:
manager approval → finance approval → processing.
No Temporal, no Airflow, no Step Functions.

Usage:
    pip install axme
    export AXME_API_KEY="your-key"
    python main.py
