在同一事件中使用多个 Boot trait将只触发第一个trait，而忽略其余的可引导trait。

class Tag extends Model
{
    use HasKey; // this will work (but if i put it bellow it will not work)
    use HasSlug; // this's not (but if i put it above it will work)
}

trait HasKey
{
    public static function bootHasKey()
    {
        static::creating(
            fn (Model $model) => $model->key = 'value'
        );
    }

trait HasSlug
{
    public static function bootHasSlug()
    {
        static::creating(
            fn (Model $model) => $model->slug = 'value'
        );
    }
}
