🛠️ Repo: 2026-06-06 Codecov outage

### Tooling Suggestion Checklist - [x] I have tried restarting my IDE and the issue persists. - [x] I have pulled the latest `main` branch of the repository. - [x] I have read and agree to Mocha's [Code of Conduct](https://github.com/mochajs/mocha/blob/main/.github/CODE_OF_CONDUCT.md) and [Contributing Guidelines](https://github.com/mochajs/mocha/blob/main/.github/CONTRIBUTING.md) - [x] I have searched for [related issues](https://github.com/mochajs/mocha/issues?q=is%3Aissue) and [issues with the `faq` label](https://github.com/mochajs/mocha/issues?utf8=%E2%9C%93&q=is%3Aissue%20label%3Afaq%20), but none matched my issue. - [x] I want to provide a PR to resolve this ### Overview 2026-06-06 19:37 PDT - Codecov checks are currently consistently failing. ### Additional Info Codecov recently changed ownership from Sentry to Harness, this may be an infra issue on their side: [2026-06-02 press release](https://www.harness.io/press-and-news/harness-acquires-codecov) This is probably not the same root cause as parent issue #6036 based on consistency: today, it's all 49 checks on all runs. Before, it was only 1 or 2 checks on ~3% of runs. Something broke recently!
