Add code quality checks and formatting configuration

- Introduced a .clang-format file to enforce Google C++ style guidelines across the codebase.
- Updated CMakeLists.txt to include custom targets for formatting and format-checking using clang-format.
- Added a quality_check.sh script to automate code quality checks, including formatting and static analysis with cppcheck.
- Enhanced CMakePresets.json with new macOS-specific configurations for ARM64 and universal binaries, improving build flexibility and support.
