Subject: [PATCH] feat: Add Code Coverage Job to CI

This commit adds a new `code-coverage` job to the CI pipeline.
This job uses `cargo-llvm-cov` to generate a code coverage report and uploads it to Codecov.

This will help us to track our test coverage and to identify areas of the codebase that need more testing.
