ci: add npm install + build check

[gbl186]

Added a basic CI build gate so broken dependency changes don’t sneak in.

---

Note

Medium Risk
Adds a new GitHub Actions build gate that will run on every PR/push; if npm run build is not defined or the build is flaky, it can start blocking merges unexpectedly.

Overview
Adds a new GitHub Actions workflow (.github/workflows/node-build.yml) that runs on pull requests and pushes to main/master, sets up Node 18, installs dependencies with npm ci, and executes npm run build as a CI build gate.

CI uses npm but project uses yarn

High Severity

The workflow uses npm ci but the project is configured to use yarn (evidenced by yarn.lock existing and no package-lock.json). The npm ci command will fail because it requires a package-lock.json file to function. This CI gate will never pass.

CI calls nonexistent build script

High Severity

The workflow runs npm run build but there's no build script defined in package.json. The project only has specific build scripts like activity:build, pnl:build, fpmm:build, etc. This command will always fail with "missing script: build".
