Add set comprehension support

[CrazyDubya]

Summary

• support ast.SetComp in analysis type inference
• translate ast.SetComp expressions to lambda-generated std::set
• infer C++ types for set comprehensions
• test set comprehension inference and conversion

Testing

• python -m pytest tests/test_code_analyzer_fixed.py::TestCodeAnalyzer::test_set_comprehension_inference -q
• python -m pytest tests/test_conversion_fixed.py::test_set_comprehension_translation -q
• python -m pytest -q (fails: test_fibonacci_conversion)

Pull Request Overview

This PR adds support for set comprehensions in the Python-to-C++ translator by implementing type inference and code generation for ast.SetComp nodes. The implementation translates Python set comprehensions into lambda-generated std::set containers in C++.

Key Changes

• Added type inference for set comprehensions in the code analyzer
• Implemented C++ code generation for set comprehensions using lambda expressions
• Added comprehensive test coverage for both analysis and conversion functionality

The tempfile import is used but os.unlink() is called for cleanup. Consider using tempfile.TemporaryDirectory() context manager or pytest's tmp_path fixture instead of manual cleanup with os.unlink().

CodeGenerator is not imported but is being instantiated. Add 'from src.converter.code_generator_fixed import CodeGenerator' to the imports.
