## Title

    Proposed fix: [PydanticAI] RuntimeError: Event loop is closed from httpx during a model request after the loop that first used the agent was closed (repeated run_sync / asyncio.run, tests)

## Body

    Recommended action: Recreate the agent together with its model and provider (or pass a fresh http_client to the provider) per event loop; avoid closing an event loop other code still uses.
    
    Option: Build a fresh Model/provider (or http_client) per event loop [evidence: official_recommended_action]
    Applies when: Pydantic AI used across multiple event loops
    Steps:
    1. Construct the provider with a new httpx AsyncClient inside the loop that will use it
    2. Create the Model and Agent from that provider inside the same loop (e.g. a pytest fixture scoped to the loop)
    Expected: Requests no longer touch connections bound to a closed loop
    
    Evidence basis (self-declared by the contributing chat client): untested.
