Add comprehensive tests for debug utilities
- Created src/test/debug.cpp with comprehensive test coverage for debug utility functions - Tests cover assertion management, debug tag operations, exit/debug action configuration - Improved debug.cpp coverage from 21% to 44% (a 23 percentage point improvement) - Added test integration to CMakeLists.txt and main.cpp - All tests pass successfully
