Add PHPUnit configuration for testing (#1)

Add PHPUnit configuration file for testing setup

- Created phpunit.xml to define testing environment and settings.
- Configured test suite to include tests from the 'tests' directory.
- Set source restrictions to include only the 'src' directory.
- Enabled strict checks for coverage metadata, deprecations, warnings, and risky tests.
