Allow users to specify a `-y` argument for not asking to execute the script

Hello,

Thank you very much for your program.

I would like to create a script with for example this command :

```
#!/bin/bash
ai -s open nemo in the home folder
```

Unfortunately it doesn't works because of the prompt :

◆ Exécuter ce script?
│ ● ✅ Oui (Allons-y!)
│ ○ 📝 Modifier
│ ○ 🔁 Réviser
│ ○ 📋 Copier
│ ○ ❌ Annuler
└

Could it be possible to add a `-y` argument for not showing this prompt ?

```
#!/bin/bash
ai -s -y open nemo in the home folder
```

Thanks ;-)

Start at the CLI entry point handling the `ai -s` command and trace how the execution confirmation prompt is selected. Add the requested `-y` invocation so the prompt is skipped, while the existing command continues to prompt without it. Verify the example shell-script usage behaves as described.
