Fix Document Preview Render for editor tool

[reyesrico]

Issue

For editor project and running npm run dev it was identified that SandoxDocumentPreview component is not rendering any text or html.

Root Cause

The Sandbox iframe tries to load assets from http://localhost:4300/chartifact/dist/v1/ but these files weren't being served by the Vite dev server.

Fix

1. Added Cross-Platform Copy Script
   File: [copy-assets]

• Uses only Node.js built-in modules
• Automatically handles path separators for each OS
• Shows friendly error message if assets aren't built yet
• Follows same pattern as existing [copy-schema.js] scripts in the project

2. Updated Package Scripts
   File: [package.json]

• postbundle: Automatically copies assets after build completes
• predev: Safety net - ensures assets exist before starting dev server
• clean: Removes copied assets when cleaning

How It Works

Build Workflow:

# From workspace root
npm run build


# From editor directory
npm run dev

Cross-Platform ✅

• Works on Windows, Mac, and Linux
• Uses only Node.js built-ins (no external dependencies)
• Follows existing project patterns

Testing

• Delete assets: rm -rf packages/editor/public/chartifact
• Build: [npm run build]
• Verify assets copied to packages/editor/public/chartifact/dist/v1/
• Start dev: npm run dev (from editor directory)
• Document Preview should work without errors ✅

Hmmm - I got the Assets not found, run npm run build in workspace root first error.
