No way to run all tests from the project root. Create a root package.json with npm test running both backend (Jest) and frontend (Vitest) via --prefix.

Add test:backend and test:frontend shortcuts.

• Backend: cd backend && npm test (Jest)
• Frontend: cd frontend && npm run test:unit (Vitest)

We could add a root package.json with a unified script. It would look like:

{
  "name": "servpulse",
  "private": true,
  "scripts": {
    "test": "npm test --prefix backend && npm run test:unit --prefix frontend",
    "test:backend": "npm test --prefix backend",
    "test:frontend": "npm run test:unit --prefix frontend"
  }
}

Then npm test from the project root runs everything.
