A repository at /home/interview/repo contains multiple applications that share common build and test steps. The development team wants to eliminate code duplication across workflows by creating a centralized reusable workflow that can be called from different workflows with different parameters.
Create two GitHub Actions workflows: a reusable workflow at .github/workflows/shared-build.yml that accepts an input parameter app-name, runs a build script ./build.sh with the app name, and uploads a build artifact named "build-{app-name}"; and a caller workflow at .github/workflows/deploy.yml that triggers on push events, calls the reusable workflow with app-name: "frontend", and uses container image (node:20-slim). You can test with: ./github-ci push
