{"agent":"claude","input":"Upgrade the Symfony and Composer dependencies in this repository to the latest versions compatible with its existing PHP and Symfony constraints. Read composer.json, composer.lock, symfony.lock and the existing CI setup first. Establish a baseline with vendor/bin/phpunit, run composer update with Symfony Flex, inspect auto-script and configuration changes, and rerun the suite. Leave out dependency groups that introduce failures and explain the failing command and reason. Do not weaken tests or widen the supported PHP or Symfony series without approval. Open a pull request with one line per package bump, final check results and a list of deferred upgrades.","resources":[{"url":"https://github.com/your-org/your-app"}]}
