Per-Agent Permissions Example with AgentOS

"""
Per-Agent Permissions Example with AgentOS

This example demonstrates how to define per-agent permission scopes
to control which users can run which specific agents.

Prerequisites:
- Set JWT_VERIFICATION_KEY environment variable or pass it to middleware
- Endpoints are automatically protected with default scope mappings

    Audience Verification:
    - Tokens must include `aud` claim matching the AgentOS ID
    - Tokens with wrong audience will be rejected
