feat: add codecov integration with test results upload#35
Conversation
- Add lcov reporter to nyc configuration for codecov compatibility - Add codecov upload steps to CI workflow for coverage and test results - Configure fail_ci_if_error: false to not block CI on codecov issues Project already has .github/codecov.yml with project and patch coverage checks configured.

📝 WalkthroughWalkthroughCI sets VSC_JUPYTER_INSTRUMENT_CODE_FOR_COVERAGE=true for the test run, then runs tests. After tests, the workflow uploads coverage to Codecov via codecov/codecov-action@v5 (uploads coverage/lcov.info, uses secrets.CODECOV_TOKEN, fail_ci_if_error: true). If the run is not cancelled, it uploads test results via codecov/test-results-action@v1 (uploads test-report.xml, uses secrets.CODECOV_TOKEN, fail_ci_if_error: true). Node test coverage reporters now include lcov alongside existing reporters (html when enabled, text, text-summary). No exported/public API changes. Sequence Diagram(s)sequenceDiagram

…t results upload - Add VSC_JUPYTER_INSTRUMENT_CODE_FOR_COVERAGE env var to test step to enable coverage generation - Add fail_ci_if_error: false to test results upload for consistency with coverage upload Addresses CodeRabbit automated review feedback on PR #35
Change fail_ci_if_error from false to true for both coverage and test results uploads to ensure CI fails when codecov upload fails, as requested by user.
