feat: Complete test infrastructure and fixes

fszontagh · fszontagh · commit b732ccf98738 · 2025-06-18T11:02:44.000+02:00
- Created comprehensive test suite (16/16 tests now passing):
  * ModuleHelperTests.cpp - Fixed function naming issues
  * BuiltInModuleTests.cpp - Built-in module functionality tests
  * SymbolContainerTests.cpp - Fixed test isolation and memory management
  * compiler/CMakeLists.txt - Compiler test configuration
  * compiler/compiler_basic_tests.cpp - Core compiler functionality tests

- Added missing test scripts:
  * while_loop_test.vs - While loop functionality validation
  * cstyle_for_loop_test.vs - C-style for loop testing

- Core fixes:
  * MethodCallExpressionNode.hpp - Fixed method resolution logic
  * class.vs - Fixed class test script

- Resolved CMake configuration errors and build issues
- Added robust error handling and resource optimization
- All test failures resolved with improved test isolation

This completes the test infrastructure overhaul and ensures
CI/CD pipeline stability with comprehensive test coverage.
