Feature: #109370 - Array-based queryParameters for page links 

Description 

When page links are created programmatically by the LinkFactory PHP API, query parameters previously had to be provided as a URL-encoded string in the additionalParams configuration key. A new queryParameters configuration key has been introduced that accepts a PHP array, including multi-dimensional arrays.

When both queryParameters and additionalParams are set, they are merged using array_replace_recursive() , with queryParameters taking precedence.

Example:

$linkFactory->create('Link text', [
    'parameter' => 42,
    'queryParameters' => [
        'tx_news' => [
            'action' => 'show',
            'id' => 123,
        ],
    ],
], $contentObjectRenderer);

The Fluid ViewHelpers <f:link.page>, <f:uri.page>, <f:link.action>, and <f:uri.action> now use this option internally to pass their additionalParams argument as an array, eliminating the previous serialize/deserialize round trip via query string encoding.

Impact 

Developers creating page links via the LinkFactory PHP API can now pass query parameters as structured arrays via the queryParameters configuration key. This avoids manual query string encoding and makes multi-dimensional parameter handling more natural.

The option can be combined with the existing string-based additionalParams. When both are provided, queryParameters values override matching keys from additionalParams.
