Add Laravel 12 Support

[sweptsquash]

This pull request includes updates to the testing matrix in the GitHub Actions workflow and several modifications to the composer.json file to support the latest versions of PHP and Laravel. The most important changes include expanding the test matrix, updating dependencies, and reorganizing the composer.json file.

Updates to testing matrix:

• .github/workflows/run-tests.yml: Added PHP 8.4 and Laravel 12.* to the testing matrix, and excluded Laravel 12.* with PHP 8.1.

Modifications to composer.json:

• composer.json: Updated illuminate/contracts, orchestra/testbench, and phpunit/phpunit dependencies to include support for Laravel 12.* and PHP 8.4.
• composer.json: Reorganized the file to move minimum-stability and prefer-stable settings, and re-added the scripts section with commands for testing and code analysis. [1] [2]
