This update introduces a new module, `puppeteerLaunchOptions.js`, which centralizes the Puppeteer launch configuration. The `getPuppeteerLaunchOptions` function is added to provide customizable launch arguments, enhancing the flexibility of browser instantiation in both `mailworker.js` and `pdffactory.js`. This refactor improves code maintainability and allows for easier adjustments to Puppeteer settings in the future.
