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
