Session ID not consistent when requerying same server_client instance #238

# 1. Create server_client and get initial session_id from seed_session
server_client = ServerClient.load_from_global_config()
reset_task = await server_client.post(
    server_name="tales",
    url_path="/seed_session",
    json={
        "framework": framework,
        "task_no": task_no,
        "max_episode_steps": max_steps,
        "seed": seed,
        "split": split,
    },
)
output = await reset_task.json()
session_id = output["session_id"]  # Store session_id manually

# 2. On subsequent calls in multi-turn loop, must explicitly pass session_id
for _ in range(25):
    # Query model...
    
    # Must manually pass session_id with each command
    action_task = await server_client.post(
        server_name="tales",
        url_path="/execute_command",
        json={"command": action, "session_id": session_id},  # <-- Manual session_id
    )
    output = await action_task.json()

server_client = ServerClient.load_from_global_config()

# Session created
reset_task = await server_client.post(server_name="tales", url_path="/seed_session", json={...})

# Subsequent calls automatically use same session without manual session_id
action_task = await server_client.post(
    server_name="tales",
    url_path="/execute_command",
    json={"command": action}  # No session_id needed
)
