Review Summary

Your implementation successfully meets all requirements. The sort2 method is correctly added to Array.prototype without modifying the native sort, uses the exact [].__proto__.sort2 pattern inside applyCustomSort, sorts arrays in place while returning the original reference, and implements default string comparison using String(a) and String(b). The custom sorting algorithm works correctly without calling the built-in sort. All test cases should pass. The bubble sort approach has O(n²) complexity, which is acceptable for this task and handles the specified use cases properly.
