chore: update Node.js version to 24

[tristandubbeld]

Summary

Updates the CodeSandbox client monorepo to use Node.js 24 across all configurations and packages.

Changes

• Updated Node.js version from 16 to 24 in:
  • .nvmrc file
  • Root package.json engines field
  • packages/components/package.json engines field
  • CircleCI executors (.circleci/config.yml)
  • CodeSandbox environment configs (.codesandbox/environment.json, .codesandbox/ci.json)
• Added sse-loading-screen to Yarn workspaces for Node 24 compatibility
• Updated sse-loading-screen package configuration to work in workspace context
• Added documentation explaining the dual package management approach (Yarn workspaces + Lerna)

Testing Instructions

1. Clean install test:

   rm -rf node_modules yarn.lock
   yarn install

   • Verify installation completes without errors
   • Check that the Lerna workspace warning appears (expected and safe to ignore)

2. Build test:

   yarn build:deps
   yarn build

   • Verify all packages build successfully

3. Development server:

   yarn start

   • Verify the app starts without errors
   • Check that the app loads correctly in the browser

4. CI/CD verification:

   • Verify CircleCI builds pass with Node 24
   • Check that CodeSandbox environment uses Node 24 correctly
