permissions-config.json commandIdentifiers with spaces still require approval

### Describe the bug

Following the examples in https://docs.github.com/en/copilot/reference/copilot-cli-reference/cli-config-dir-reference#examples I'm trying to add "make fix" as command to be automatically allowed and it's not working, permission is always requested.

OTOH adding just "make" makes all make commands automatically allowed.

### Affected version

GitHub Copilot CLI 1.0.71.

### Steps to reproduce the behavior

1. Write this in `~/.copilot/permissions-config.json`
```json
{
"locations": {
"/some/path": {
"tool_approvals": [
{
"kind": "commands",
"commandIdentifiers": [
"make fix",
"make:fix",
"make(fix)",
"shell(make fix)",
"bash(make fix)"
]
}
]
}
}
}
```
2. `cd /some/path && copilot`
3. say "run make fix"

### Expected behavior

no questions asked

### Additional context

_No response_

首先使用 ~/.copilot/permissions-config.json 和列出的 commandIdentifiers 重现批准行为，然后跟踪 Copilot CLI 的命令批准处理流程。完成的标准是：在完成配置后，"make fix" 无需批准即可运行，同时现有的更宽泛的 "make" 行为仍保持正确。
