Subject: [PATCH] ci: upload code coverage on PRs

Add actions/upload-code-coverage@v1 step to the CI workflow so the
Cobertura report produced by vitest is uploaded to GitHub's code
coverage API. Restricted to the ubuntu-latest + Node 22.x matrix entry
to avoid duplicate uploads, and uses fail-on-error: false so transient
API failures don't break CI.
