When starting a new session, the side panel is not visible.

When starting a new session, the side panel is not visible. I want access to the files, and terminal, and browser so i can se what i want to change before prompting. That way i can use this app and not have to run things in VS CODE before prompting

在 macOS 上的应用版本 1.1.8 中，从 /chat 路径开始一个新会话，以复现该问题。将会话开始时的行为与预期结果进行核对：侧边面板应可见，并在显示提示之前提供对文件、终端和浏览器的访问。
