Release v0.3.45

Release 0.3.45

Changelog

Fixed

• CI (Symfony 8 matrix): set Composer platform.php to 8.4.1 (not 8.4) so Symfony 8.1 packages that require php >=8.4.1 resolve on PHP 8.4/8.5 runners.

Changed

• CI / Actions: bumped actions/checkout to v6, codecov/codecov-action to v6, and softprops/action-gh-release to v3 (workflows ci.yml, release.yml, sync-releases.yml).
• Dependencies: bumped root and Symfony 7 demo composer.lock (e.g. PHP CS Fixer).
