Subject: [PATCH 1/2] feat(ci): add GitHub native code coverage upload

- Add cobertura reporter to vitest coverage config
- Add code-quality:write permission to CI workflow
- Upload coverage via actions/upload-code-coverage@v1 on Node 20.x only
- Other Node versions (18.x, 22.x) run tests without coverage to avoid duplicate uploads
