Add Laravel 13 support

[PoloStyle07]

Summary

Adds Laravel 13 support so the package isn't dropped when users upgrade.

• composer.json: illuminate/console, illuminate/contracts and illuminate/support now allow ^13.0; orchestra/testbench allows ^11.0.
• composer.lock: content hash refreshed only. Still pins the lowest stack (PHP 8.1 / Laravel 10), so local dev is unchanged.
• Test fix: Laravel 13 ships Symfony Console 8, which removed Application::add(). The test now binds the command with $command->setApplication(), which works on Symfony 6–8. No changes to the package source were needed.
• CI: the workflow now runs a PHP × Laravel matrix (16 jobs). Previously every job ran composer install from the lock file, so only Laravel 10 was ever tested. Each job now removes the platform.php pin and installs its own Laravel/Testbench version.

Notes

• CI passes --no-security-blocking to composer update. Laravel 10 and 11 are end-of-life with unpatched advisories, and Composer 2.10 won't install them otherwise. This only affects the test install, not users of the package.
• fail-fast is now false so one failing version doesn't cancel the others.

Testing

Ran locally on PHP 8.4, installing each version the way the new CI job does:

Laravel	Symfony Console	Tests
10.50.3	6.4.46	72 passed
11.56.1	7.4.19	72 passed
12.69.2	7.4.19	72 passed
13.31.0	8.1.7	72 passed, Pint clean

Other PHP versions are covered by the CI matrix.
