Extends support to Laravel 13 and Pest v4 alongside existing Laravel 9–12 and Pest v1–3 support.

Changes

• composer.json: Added ^13.0 to all illuminate/* constraints (redis, support, database, collections), ^11.0 to orchestra/testbench, and ^4.0 to pestphp/pest and pestphp/pest-plugin-laravel
• run-tests.yml: Added PHP 8.4 matrix entries for both Laravel 12.* / testbench 10.* and Laravel 13.* / testbench 11.*; added explicit pest version pins to all matrix entries (4.* for PHP 8.4, 3.* for PHP 8.3, 2.* for PHP 8.2, 1.* for PHP 8.1) and updated the install step to require the pinned pest version
