[TypeDeclaration] Skip recursive dim fetch closure in StrictArrayParamDimFetchRector

[TomasVotruba]

Reproducer

StrictArrayParamDimFetchRector gives a false positive on recursive closures that walk an ArrayAccess tree (real case: Symfony FormView in Mautic's FormThemeTrait):

$findThemes = function ($form, $formView) use (&$findThemes): void {
    foreach ($form as $name => $field) {
        $fieldView = $formView[$name];       // $formView is a FormView (ArrayAccess), not array
        $findThemes($field, $fieldView);      // element fed back as the same param
    }
};

$findThemes($form, $formView);

The rule added array $formView, which is wrong — FormView implements ArrayAccess.

Why it happens

The closure param $formView is untyped, so PHPStan sees mixed inside the closure; the only proof it is a FormView lives at the call site, which the rule does not inspect. Seeing just $formView[$name], the rule assumes array.

Fix

Skip when a value read from $param[dim] (directly, or via a variable assigned from it) is fed back as an argument into the same closure/function (recursion — detected via the closure's by-ref use self-reference or a function's own name). Using an element as the container again is a strong tell for an ArrayAccess tree, not a plain array.

Conservative: only this recursive-feed shape is skipped; the existing changing fixtures are unaffected.
