gologinapp/gologin ? reverse-engineered prompt

Build me a simple Node.js SDK for GoLogin that lets someone use their API token to manage browser profiles and start a browser session they can automate. I want it to cover the main flow really cleanly, create a new profile with a random fingerprint, optionally create one with custom settings, list or update profiles through the API, add cookies, set or change a proxy, refresh fingerprints, and launch a profile so the caller gets back something they can use with browser automation tools like Puppeteer, Playwright, or Selenium. It should also support stopping or exiting the browser cleanly and syncing profile data back when needed.

Please make the package feel easy to use for regular developers, with clear method names, basic validation, and a couple of working examples that show creating a profile, adding a GoLogin proxy, opening a page, then closing everything down. Include TypeScript typings if possible and keep the docs practical. If anything is unclear, look up the current GoLogin API docs online and match the SDK to that.
