No active shell session

### Describe the bug

OS: Pop OS LTS 22.04
Shell: /bin/bash 5.1.16(1)-release
Copilot: GitHub Copilot CLI 1.0.32

Copilot doesn't seem able to execute shell commands. It took about two minutes to generate this output. The log indicates initialization timed out.

### Affected version

GitHub Copilot CLI 1.0.32

### Steps to reproduce the behavior

`copilot --log-interactive-shells`

[shell-0-1776516585182.log](https://github.com/user-attachments/files/26854973/shell-0-1776516585182.log)

```
❯ run echo hello using your bash shell tool

● Running a quick shell command to print "hello" using bash. Reported intent alongside the command.

● Print hello to stdout (shell)
│ echo hello
└ 1 line...

✗ Read shell output Waiting up to 2 seconds for command output
└ Invalid shell ID: 0. Please supply a valid shell ID to read output from.

● hello
```

### Expected behavior

"hello" appears in a timely manner without errors

### Additional context

_No response_

使用 `copilot --log-interactive-shells` 重现问题，并检查附加的 `shell-0-1776516585182.log` 以查找初始化超时。跟踪交互式 shell 的启动和命令执行路径；当 `echo hello` 能够快速完成且没有无效的 shell ID 或 shell 输出错误时，即表示完成。
