Not able to use session name to retrieve session in CLI

### Describe the bug

Previously, we were using the session name and were able to retrieve sessions by passing the name parameter. However, this behaviour has now changed, and the system requires the session ID instead in order to retrieve the sessions.

### Affected version
GitHub Copilot CLI 1.0.16-1

### Steps to reproduce the behavior

Resume is now hacing sessionId parameter and we used session name earlier

/resume [sessionId]

### Expected behavior

session name should be used to retrieve sessions stored on device

### Additional context

_No response_

从 CLI 的 `/resume [sessionId]` 入口点开始，跟踪该参数如何用于查找已存储的会话。使用 GitHub Copilot CLI 1.0.16-1 重现这一行为，然后验证会话名称可以检索已存储的会话，同时仍支持通过 session-ID 进行检索。
