Why don't you try that event of deleting the project make the magic.

In your Project Model add:

public static function boot() {
        
        parent::boot();

        // This method will be called before deleting $project 
        
        static::deleting(function($project) { 
             
            $project->devis()->delete();   
        
        });
    }

In your Devis Model add:

// This method will be called before deleting $devis 
public static function boot() {
        
        parent::boot();

        static::deleting(function($devis) { 

             $devis->articals()->delete();
             
        });
    }
  

So you can simply

$project->delete();
