test(phpunit): Update PHPUnit configuration and add HelpersTest

- Exclude 'src/Support/Rectors/' and 'src/Support/ComposerScripts.php' from coverage
- Add new test file 'HelpersTest.php' for support functions
- Ensure functions 'escape_argument' and 'str_snake' are tested appropriately

This change improves test coverage and ensures relevant functions are validated.
