PR metadata/description says this change only bumps phpstan/phpstan to ^2.0, but this hunk also introduces a new dev dependency (phpstan/phpstan-strict-rules) and changes the phpstan script memory limit. Please update the PR title/description to reflect the additional scope (or split these changes into a separate PR) so reviewers/CI expectations match the actual diff.

[Copilot]

This change adds phpstan-strict-rules via an include, which is additional scope beyond the PR description (“Updated phpstan/phpstan to version 2.x”). Please ensure the PR metadata is updated to mention strict rules being enabled (since it can materially change the analysis baseline).
