Add std math translation

[CrazyDubya]

Summary

• handle math.sqrt, math.sin, and math.cos in _translate_expression
• document mapping of Python math functions to C++
• add unit tests for translation logic
• fix tuple handling in analyzer to keep existing tests passing
• allow CodeGenerator to work with AnalysisResult objects

Testing

• pytest -q

Pull Request Overview

This PR extends the Python-to-C++ transpiler to handle additional mathematical functions from Python's math module. The changes implement translation of math.sqrt, math.sin, and math.cos to their C++ std:: equivalents, along with comprehensive testing and documentation updates.

Key changes:

• Enhanced expression translation logic to map Python math functions to C++ standard library equivalents
• Added comprehensive unit tests for the new math function translations
• Updated documentation to reflect the new conversion patterns

• [nitpick] The import references 'code_generator_fixed' which suggests this is a temporary or patched version. Consider using a more descriptive name or importing from the main code_generator module if this is the intended implementation.
