Pull Request Overview

This PR refines the recursive call analyzer to only report diagnostics when a method calls itself with the exact same parameters, and adds tests to cover non-identical argument scenarios.

• Analyzer now checks that each argument is a direct reference to the corresponding parameter before reporting recursion.
• Tests added for calls with different literals and for the classic Factorial(n - 1) pattern.
• Removed an unused using directive in the test file.

• [nitpick] Add tests for other argument-passing patterns, such as named arguments and ref/out parameters, to ensure the analyzer correctly allows or flags those recursive calls.
