fatal error: concurrent map read and map write with `config set` command on Windows

### Describe the problem

Hello, I have updated from 1.2.2 to 1.4.1 CLI, and my integration tests started to fail on Windows

### To reproduce

My CI code tries to set the config path, but fails with a go panic. I have this test set up for some time, and I have not hit this error before.

The error in Node.js:

```
_aborted: false,
    _options: { timeout: undefined, persist: false, throwOnError: true },
    _command: 'D:\\a\\trbr\\trbr\\.arduino-cli\\arduino-cli.exe',
    _args: [
      'config',
      'set',
      'directories.data',
      'D:\\a\\trbr\\trbr\\.test-resources\\envs\\cli\\Arduino15',
      '--config-file',
      'D:\\a\\trbr\\trbr\\.test-resources\\envs\\cli\\arduino-cli.yaml'
    ],
```

```

### Expected behavior

config set does not fail regardless of the OS.

### Arduino CLI version

1.4.1

### Operating system

Windows

### Operating system version

Microsoft Windows Server 2025, 10.0.26100, GitHub Action Runner image `windows-2025`

### Additional context

_Update:_

> I have updated from 1.2.2 to 1.4.1 CLI

I am not saying the panic is OS or version update related.

Since then, I could not reproduce the failure. Perhaps it's a race condition when setting the config file and reading the auto-update value.

### Issue checklist

- [x] I searched for previous reports in [the issue tracker](https://github.com/arduino/arduino-cli/issues?q=)
- [x] I verified the problem still occurs when using the [nightly build](https://arduino.github.io/arduino-cli/dev/installation/#nightly-builds)
- [x] My report contains all necessary details
