PR Summary

• Workflow Environment Variable Updates In this pull request various workflow files were updated, specifically within the .github/workflows directory. The changes relate to a modification in the environment variable COMPOSER_ROOT_VERSION, which was updated to 1.2.0 from 1.0.0. This change affects the versions used during CI/CD operations, aiming to improve compatibility and performance.

• Bug Fix in CHANGELOG Updates were made to the CHANGELOG.md file, including a new bug fix under version 1.2.1. The said bug fix resolves an issue (#777) related to the Query::count() method, which inaccurately returned the count if the output exceeded PHP_INT_MAX.

• Improvement of Query.php Method Modifications were made to the count() method found in src/Query/Query.php file to better manage situations where results surpass PHP_INT_MAX. Now, instead of construing the count as an integer, it will transmit the count as a string in these scenarios, helping to maintain accuracy.

• New Test Case A fresh test case was added to the tests/AbstractQueryTest.php file to check how the improved count() method performs when the result exceeds PHP_INT_MAX. The test sets up a pseudo instance of the Query class and anticipates the queryScalar() method to revert with a string value of 12345678901234567890. Consequently, the revised count() method is expected to return a string value in such cases, ensuring faithful representation of results.
