feat: Refactor CI workflows for improved coverage reporting

- Remove coverage reporting steps from `ci.yml` and create a new `coverage.yml` workflow for dedicated test and coverage collection.
- The new workflow includes steps for setting up Python, installing dependencies, running tests with coverage, and uploading results to Codecov.

Tested the new coverage workflow, and it successfully runs tests and uploads coverage reports without issues.
