Symfony Translator recipe

Kaly’s native Translator covers message catalogs. For ICU, loaders, or an existing Symfony catalog, bind the adapter — the framework keeps calling its small TranslatorInterface, Symfony does the heavy lifting:

use Kaly\I18n\Adapter\SymfonyTranslator;
use Kaly\I18n\TranslatorInterface;
use Symfony\Component\Translation\Loader\PhpFileLoader;
use Symfony\Component\Translation\Translator as SymfonyEngine;

$engine = new SymfonyEngine('en');
$engine->addLoader('php', new PhpFileLoader());
$engine->addResource('php', __DIR__ . '/lang/messages.en.php', 'en');

$definitions->set(TranslatorInterface::class, new SymfonyTranslator($engine));

Locale selection stays Kaly’s (LocaleResolver, RouteLocale), per-render binding stays LocalizedTranslator: only the translation engine changes. See i18n.
