US1.2: Setup CI/CD, linting, testing framework

[ecarrenolozano]

As a developer
I need set up continuous integration and delivery (CI/CD), along with linting and a testing framework,
So thatcode quality is maintained automatically, and changes can be tested and deployed reliably.

Details and Assumptions

• The Python Project template created at Saezlab generate workflows automatically.
• Ensure all the workflows run properly

Acceptance Criteria

• A CI workflow (e.g., GitHub Actions, GitLab CI, etc.) is configured to run on each push and pull request.
• Linting is set up using tools like ruff or flake8 and runs automatically in CI.
• A testing framework (e.g., pytest) is integrated and runs tests as part of the CI pipeline.
• The CI pipeline fails if linting or tests do not pass.
• The setup includes a badge in README.md indicating build status.
