// ── One-command Setup ──────────────────────────────────────────────
// Run via: npm run setup
// Does the following in order:
//   1. npm install (Node.js dependencies)
//   2. pip install -r requirements.txt (Python dependencies)
//   3. playwright install firefox chromium (Playwright browsers)
//   4. Copies .env.example to .env.local if not exists
//   5. --self-heal flag: runs build check + auto-generates missing modules
//
// All steps are cross-platform (Windows, Mac, Linux).
