Separate build and test jobs for clearer CI structure

- Rename build-and-test job to just 'build' for clarity
- Remove unit tests from build job (keep build focused on artifacts)
- Fix job dependencies: lint → build → browserstack-test
- Build job now only: generates test doc, builds JAR, uploads artifacts
- Integration tests run in separate browserstack-test job
- Matches cleaner separation of concerns pattern
