Process completed with exit code 2.

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/http-kernel ^7.0|^8.0 -> satisfiable by symfony/http-kernel[v8.0.12, v8.0.13, v8.0.14, v8.0.15]. - symfony/http-kernel[v8.0.12, ..., v8.0.15] require symfony/http-foundation ^7.4|^8.0 -> found symfony/http-foundation[v7.4.0, ..., v7.4.21, v8.0.0, ..., v8.1.9] but these were not loaded, because they are affected by security advisories ("�]8;;https://symfony.com/cve-2026-108082�\PKSA-xmwy-rmx5-m7h4�]8;;�\", "�]8;;https://symfony.com/cve-2026-48736�\PKSA-y6py-qpv1-h52p�]8;;�\"). Go to https://packagist.org/security-advisories/ to find advisory details. To ignore the advisories, add their IDs to the "policy.advisories.ignore-id" config or add the package to "policy.advisories.ignore". To turn the feature off entirely, you can set "policy.advisories.block" to false. Problem 2 - Root composer.json requires symfony/maker-bundle ^1.68 -> satisfiable by symfony/maker-bundle[1.68.0]. - symfony/maker-bundle 1.68.0 requires symfony/config ^7.4|^8.1 -> found symfony/config[v7.4.0, ..., v7.4.17, v8.1.0, ..., v8.1.5] but these were not loaded, likely because it conflicts with another require. Problem 3 - Root composer.json requires roach-php/core ^3.2 -> satisfiable by roach-php/core[v3.2.0, v3.2.1]. - roach-php/core v3.2.0 requires php ~8.2.0 || ~8.3.0 -> your php version (8.4.26) does not satisfy that requirement. - roach-php/core v3.2.1 requires symfony/console ^7.0 -> found symfony/console[v7.0.0, ..., v7.4.21] but these were not loaded, likely because it conflicts with another require.
