Subject: [PATCH] Add tests and continuous integration

Add unit tests and CI workflow for the repository.

* **Unit Tests**
  - Add `tests/test_example1.py` with unit tests for `add`, `subtract`, `multiply`, and `divide` functions, including edge cases like division by zero.
  - Add `tests/test_example2.py` with unit tests for `greet` and `farewell` functions, including tests for different names.

* **CI Workflow**
  - Add `.github/workflows/ci.yml` to set up GitHub Actions workflow to run tests on each commit.
  - Use Python 3.8 for the testing environment.
  - Install dependencies and run tests using `pytest`.

* **README.md**
  - Add a badge to show the build status of the repository.
