Make Coveralls conditional to avoid firewall blocks in CI

- Only load Coveralls when CI env and COVERALLS_REPO_TOKEN are present
- This prevents connection attempts to coveralls.io when not configured
- Tests will run successfully without coverage reporting by default
- To enable coverage, add COVERALLS_REPO_TOKEN secret to GitHub Actions
