#     Client for the Tool Use Env 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 ToolUseEnv(base_url="http://localhost:8000") as client:
#         ...     result = client.reset()
#         ...     print(result.observation.echoed_message)
#         ...
#         ...     result = client.step(ToolUseAction(message="Hello!"))
#         ...     print(result.observation.echoed_message)

#     Example with Docker:
#         >>> # Automatically start container and connect
#         >>> client = ToolUseEnv.from_docker_image("tool_use_env-env:latest")
#         >>> try:
#         ...     result = client.reset()
#         ...     result = client.step(ToolUseAction(message="Test"))
#         ... finally:
#         ...     client.close()
