cancel tests on new commit (#3028)

Auto-generated PR for: cancel tests on new commit

## Summary by cubic
Cancel in-progress GitHub Actions runs when a new commit is pushed to
the same branch or PR. This cuts wasted CI minutes and speeds up
feedback.

- **Refactors**
- Added concurrency with cancel-in-progress: true to workflows: test,
lint, package, publish, docker, cloud_evals.
- Used group: ${{ github.workflow }}-${{
github.event.pull_request.number || github.ref }} to scope per workflow
and branch/PR.
