Fix GitHub Actions workflow hanging issue

- Rename job from 'build' to 'test' to avoid conflicts with ci.yml
- Add timeout-minutes: 30 to prevent indefinite hanging
- Add pull_request trigger for better PR testing
- Improve job naming and step organization
- Split dependency installation into separate steps for better debugging

This should fix the 'Waiting for status to be reported' issue.
