⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: tools/composer.lock

Command failed: composer update phpstan/phpstan-phpunit:2.0.1 --with-dependencies --ignore-platform-req='ext-*' --ignore-platform-req='lib-*' --no-ansi --no-interaction --no-scripts --no-autoloader --no-plugins
Loading composer repositories with package information
Dependency phpstan/phpstan is also a root requirement. Package has not been listed as an update argument, so keeping locked at old version. Use --with-all-dependencies (-W) to include root dependencies.
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires phpstan/phpstan-phpunit ^2.0.1 -> satisfiable by phpstan/phpstan-phpunit[2.0.1].
    - phpstan/phpstan-phpunit 2.0.1 requires phpstan/phpstan ^2.0 -> found phpstan/phpstan[2.0.0, 2.0.1] but it conflicts with your root composer.json require (^1.12.10).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
