Add GitHub Actions CI workflow to run CMake build and tests

[ovelhaaa]

Motivation

• Add an automated CI workflow to run the project build and unit tests on each push and pull request using GitHub Actions.

Description

• Create .github/workflows/ci.yml which triggers on push and pull_request, checks out the repo, runs CMake configure, builds the project, and runs tests with ctest on ubuntu-latest.

Testing

• Ran cmake -S . -B build -DCMAKE_BUILD_TYPE=Release && cmake --build build --config Release --parallel && ctest --test-dir build --output-on-failure, and all tests passed (5/5 tests, 100% passed).
