Pull Request Overview
This PR enhances the mistyped-exponentiation query in Go to better detect XOR operations that might be mistaken for exponentiation by including constants with likely bitmask values in the detection logic.
- Adds support for detecting XOR operations involving declared constants that have hexadecimal or octal initializers
- Updates the test case to include constant declarations with hexadecimal values to verify the enhanced detection
