Pull request overview

This PR adds a GitHub Actions CI workflow that runs cpplint, a C++ style linter, on the repository's source code. It is intended to enforce code style standards by scanning C++ files on pushes and pull requests targeting main and develop branches.

Changes:

• Adds a new cpplint.yml GitHub Actions workflow that installs and runs cpplint with --recursive and various --exclude options.
• Configures concurrency settings to cancel in-progress runs when a newer run is triggered on the same PR.
• Sets the workflow to run on push/PR events targeting main and develop, with paths-ignore for docs and markdown files.

Error here in actions was fixed with PR #5 , so I think if you pull from main that should fix it. Though unsure if my code passes linter haha.

Thanks @MahirEmran, pulling from main fixed it. @j4lando should be ready to review whenever you’re free (I know you’ve got midterms going on so no rush, gl!)
