Apply the new Rector suggestion in Debugger #634

Summary

Add the closure parameter type that Rector 2.8.3 asks for in Debugger::routeInfo(), so composer rector:check passes again.

Why

The CI workflow runs composer update, so it installs the newest Rector. Rector 2.8.3 reports one change that the earlier version did not, and every pull request now fails the Rector step on PHP 8.1, 8.2 and 8.3:

src/Debugger/Debugger.php:249
-        return array_filter($info, fn ($value): bool => $value !== null && $value !== []);
+        return array_filter($info, fn (string|array|null $value): bool => $value !== null && $value !== []);
Applied rules: AddArrayFunctionClosureParamTypeRector

Scope

• Apply that one change in src/Debugger/Debugger.php.
• Rector also warns that the rule DeclareStrictTypesRector registered in the Rector config is deprecated and will be removed. That is not part of this ticket; it needs its own change before the rule is removed.

Acceptance Criteria

• composer rector:check, composer cs:check, composer phpstan and the Debugger tests pass
• no behavior change
