    Client for the Executive Inbox Environment.

    This client maintains a persistent WebSocket connection to the environment server,
    enabling efficient multi-step interactions with lower latency.
    Each client instance has its own dedicated environment session on the server.

    Example:
        >>> # Connect to a running server
        >>> with ExecutiveInboxEnv(base_url="http://localhost:8000") as client:
        ...     result = client.reset()
        ...     print(result.observation.output)
        ...
        ...     result = client.step(ExecutiveInboxAction(action_type="get_calendar"))
        ...     print(result.observation.output)

    Example with Docker:
        >>> # Automatically start container and connect
        >>> client = ExecutiveInboxEnv.from_docker_image("executive_inbox-env:latest")
        >>> try:
        ...     result = client.reset()
        ...     result = client.step(ExecutiveInboxAction(action_type="get_calendar"))
        ... finally:
        ...     client.close()
