Exception on Compiled Closure Routes

### Scribe version

5.2.1

### PHP version

8.4.7

### Laravel version

12.16.0

### Scribe config

```ruby
Does not matter in this case
```

### What happened?

If you have a closure route:
`
Route::get('/test', function () {
return response()->json([]);
});
`
And run laravel's optimization: `php artisan optimize`
Then run scribe's generation: `php artisan scribe:generate`
Throws error because scribe is trying to look for a controller and an action to look into it.

```

The issue is here: `Knuckles\Scribe\Tools\Utils::getRouteClassAndMethodNames()`
It checks only for normal routes. It does not know about closure routes.
I know its an edge case, but still.

### Docs

- [x] I've checked [the docs](https://scribe.knuckles.wtf/laravel), the [troubleshooting guide](https://scribe.knuckles.wtf/laravel/troubleshooting), and [existing issues](https://github.com/knuckleswtf/scribe/issues?q=is%3Aissue+), but I didn't find a solution

Start in src/Tools/Utils.php at getRouteClassAndMethodNames(), then trace how GroupedEndpointsFromApp uses its result during scribe:generate. Reproduce with a closure route after php artisan optimize and confirm that generation no longer throws CouldntGetRouteDetails for that route.
