Example demonstrating background execution with a Team

"""
Example demonstrating background execution with a Team.

Background execution allows you to start a team run that returns immediately
with a PENDING status, while the actual work continues in the background.
You can then poll for completion or cancel the run.

Requirements:
- PostgreSQL running (./cookbook/scripts/run_pgvector.sh)
- OPENAI_API_KEY set

Usage:
    .venvs/demo/bin/python cookbook/03_teams/14_run_control/background_execution.py
