Implement Automated Testing and CI/CD for Dev Branch

[XDftr]

Objective Ensure that merging the dev branch into main requires all tests to pass by setting up automated testing and a CI/CD pipeline.

Functionalities:

Automated Testing:

• Configure CI/CD to run ./gradlew test on every push and pull request to the dev branch.

CI/CD Pipeline:

• Set up GitHub Actions to automate the testing process.

Merge Restrictions:

• Enforce that merging dev into main is only possible if all tests pass successfully.

Branch Protection

• Configure branch protection rules on the main branch to require passing status checks before merging.
