Code Review
This pull request is a great initiative to improve code quality by integrating clang-tidy for static analysis. The initial configuration and the fixes for the issues it found are well-implemented. I've provided a few suggestions to make the CI check more robust and comprehensive. The most critical point is to ensure all source files are analyzed, as the current implementation only checks a small subset. I've also suggested improvements to the configuration for better consistency and to leverage more of clang-tidy's capabilities.

The use of head -5 here severely limits the scope of the static analysis, as it will only check the first 5 .cpp files it finds. This undermines the goal of having a comprehensive static analysis check in CI. Please remove head -5 to ensure all source files are checked.
Additionally, it's better practice to configure warnings-as-errors in the .clang-tidy file rather than as a command-line argument. This ensures consistent behavior for developers running the tool locally. I've added a suggestion on the .clang-tidy file to move this setting.

This is a good initial set of checks. To further improve code quality, consider enabling more check groups. clang-tidy offers many useful checks that can catch subtle bugs and performance issues. For example, you could enable broader sets of checks like bugprone-*, performance-*, and modernize-*, and then explicitly disable any specific checks that are too noisy for this project. This iterative approach will help maximize the benefits of static analysis.

To ensure clang-tidy behaves consistently for all developers and in CI, it's best to configure it to treat warnings as errors directly in this file. This should be done in conjunction with removing the --warnings-as-errors='*' flag from the Makefile command.
