// Create default configuration
const defaultConfig = {
  language: 'en',
  security: { rateLimit: { enabled: true } },
  performance: { enableOptimizations: true },
};

// Set secure permissions (Unix systems)
await fs.chmod(CONFIG_DIR, 0o700); // rwx------
```

#### Release Management Script (`scripts/release.js`)

**Purpose**: Comprehensive release automation with quality gates

**Release Process**:
