{"agent":"claude","input":"Upgrade this project's Composer dependencies to their latest compatible releases, keeping config.platform.php and extra.symfony.require in composer.json as they are. Run composer outdated --direct first, then update one package family at a time with composer update --with-dependencies: the symfony packages together, doctrine together, twig together, then the dev tools. After each family run vendor/bin/phpunit, vendor/bin/phpstan analyze, composer audit and the console lint commands .github/workflows/lint.yaml runs (lint:yaml config, lint:twig templates, lint:xliff translations, lint:translations, lint:container, doctrine:schema:validate --skip-sync). Revert any family that fails any of them and record the failing test, deprecation or phpstan message. Open one pull request listing each bump with its old and new locked version, each config file Flex rewrote, and each skipped upgrade with the error that blocked it.","resources":[{"url":"https://github.com/your-org/your-app"}]}
