Add phpunit-watcher for improved testing and customization

[fadrian06]

This pull request updates the project's test-watching setup to improve reliability and configuration consistency. The main changes involve ensuring the spatie/phpunit-watcher dependency is managed directly by Composer, simplifying the test watcher script, and reordering settings in the phpunit-watcher.yml file for clarity.

Dependency management:

• Added spatie/phpunit-watcher as a development dependency in composer.json to ensure it is always available and versioned with the project.

Test script simplification:

• Updated the test-watcher script in composer.json to directly run phpunit-watcher watch, removing the previous logic that attempted to install it globally if missing.

Configuration cleanup:

• Reordered and regrouped sections in phpunit-watcher.yml for consistency, moving the watch section to the end and ensuring notification and PHPUnit settings are clearly organized. No functional changes, but improves readability and maintainability.
