Complete test suite containing 17 unit and feature tests covering core captcha logic, math and text generators, validation rules, and Intervention Image generation.
Added phpunit.xml for package test execution.
Added .gitignore to prevent tracking vendor/, composer.lock, and PHPUnit cache.
Full compatibility with Laravel 13 (illuminate/* versions ^13.0).

Proper Rewrite: Rewrote all classes to use PHP 8.2+ features, including declare(strict_types=1);, native type hints, parameter/return type declarations, and constructor property promotion.
Performance Optimization: Replaced the extremely slow bcrypt hashing (Hash::make()) of the plain captcha answer for session identifiers with a fast, secure, cryptographically random token (Str::random(40)).
Swapped deprecated rand() and mt_rand() functions for secure random_int().
Updated intervention/image dependency constraints in composer.json to ^3.0.

Fixed array mapping syntax bug in CaptchaServiceProvider.php where a comma was used instead of => inside the publishes configuration array.
