refactor: Update tests.yml to install lcov and check code coverage

This commit updates the tests.yml file to install lcov and check the code coverage. It adds a new step to install lcov and jq dependencies using apt-get. It also modifies the check-coverage step to generate lcov.info, filter out specific files, and calculate the code coverage percentage. The threshold is set to 50%, and if the coverage is below the threshold, the step will exit with an error. This change improves the accuracy of the code coverage report and ensures that the correct files are included/excluded.
