This PR adds support for displaying the APP_RUNTIME value in the Symfony Profiler configuration dashboard.

Before

  • The configuration dashboard did not show which application runtime was used.

After

  • A new section "Application Runtime" is displayed when $_SERVER['APP_RUNTIME'] is set, making it easier to debug and confirm the active runtime.
$_SERVER['APP_RUNTIME'] = 'Symfony\\Runtime\\SymfonyRuntime';

Profiler UI

Application Runtime
-------------------
Runtime: Symfony\Runtime\SymfonyRuntime

If APP_RUNTIME is not defined the runtime class will be the one defined in composer.json’s extra.runtime.class, or the SymfonyRuntime by default.

If the goal of this PR is only to display APP_RUNTIME’s value, the profiler already has a Server Parameters tab in the Request panel.

Hey thx for trying that
Indeed this env var alone is not worth it
My main idea in the issue was if we can display, in the profiler or perhaps also the console about command, the real runtime behind the scene from wherever it can come from
(Dont know the feasability thought)

profiler: display resolved application runtime class in Config panel
567a4ed 
- Resolve runtime from APP_RUNTIME, composer.json extra.runtime.class, or Symfony\Runtime\SymfonyRuntime
- Expose via ConfigDataCollector::getAppRuntime and render in config.html.twig
- Add tests for env/composer/fallback resolution

The PR now displays the resolved runtime class — it checks APP_RUNTIME, then composer.json's extra.runtime.class, and finally falls back to Symfony\Runtime\SymfonyRuntime if none are set. So it shows the actual runtime behind the scenes, not just the env var.
