Feat/ci cd pipeline

[OperaCode]

Description

Fixes #91

This PR enhances the existing CI pipeline by adding automated test coverage reporting and integrating Codecov for coverage tracking.

This update extends the current workflow by:

• Running tests with coverage enabled (--coverage)
• Adding a Codecov upload step to publish coverage results
• Ensuring CI does not fail if Codecov is not configured (fail-safe handling)

This improves visibility into code quality and lays the foundation for future test coverage improvements.
