…ge check

This commit modifies the tests.yml file to remove the lcov filtering step and update the coverage check. It replaces the previous lcov command with a new one that includes all files in the coverage report. Additionally, it updates the coverage check step to calculate the coverage percentage based on the lcov.info file. This change simplifies the workflow and ensures accurate code coverage measurement.
