test(ci): add checks permission, turbo cache, dual reporters

- Add checks: write so junit-report can create check runs
- Add turbo cache step to skip unchanged build dependencies
- Use dual reporters (default + junit) for readable console output
- Replace annotate_only with check_name for proper check runs
- Guard set -o pipefail for Windows compatibility
