Creates a Vercel-compatible environment file from the web app's .env.local file

create-vercel-env.js

#!/usr/bin/env node

/**
 * Creates a Vercel-compatible environment file from the web app's .env.local file
 * 
 * This script converts the generated .env.local file into a format that can be 
 * imported directly into Vercel's environment variables dashboard.
 * 
 * Key differences from .env.local format:
 * - Removes quotes around values (Vercel adds them automatically)
 * - Strips comments and empty lines
 * - Maintains all variable names and values exactly as they are
 * 
 * Usage:
 *   1. First run: node scripts/sync-env.js --env prod
 *   2. Then run: node scripts/create-vercel-env.js
 *   3. Upload the generated vercel.env file to Vercel Dashboard
