Feature/jacoco coverage

[davide954]

This PR adds the JaCoCo Maven plugin to generate code coverage reports during the build process(Fixes #136)

Changes

• Added jacoco-maven-plugin to pom.xml.
• Configured execution to automatically generate reports after tests.

How to test

You can generate the coverage report by running the standard test command in your terminal:

mvn clean test

Where to check results

Once the build completes successfully, the report is generated in target directory.

• Open the file target/site/jacoco/index.html in your browser as localhost.
• You will see a breakdown of code coverage per package/class (green bars indicate covered code, red indicates missed branches).

Can you add to the description of the PR an explanation on how this is used from the console, where to check the results etc...?

Not everyone is familiar with JaCoCo so this could be useful

Thanks @davide954

I've set the threshold to 0.60 as the current instruction coverage is 60%. This ensures that future PRs won't decrease the test quality.

Let me know if the description of the PR looks good.
