fix: resolve CLI argument parsing and memory safety issues
- Fix argument filtering logic to only filter --config when present - Fix CLI argument count calculation in backward compatibility test - Add memory safety checks to YAML parsing functions - Downgrade to yaml-cpp 0.7.0 for better platform compatibility Local tests now pass successfully.
