faisalman/ua-parser-js ? reverse-engineered prompt

Build me a JavaScript library that can look at a user agent string and tell me what browser, operating system, CPU, device type, and model it came from, plus whether it looks like a bot, crawler, app, or AI agent.

I want it to work both in the browser and in Node, and I’d like it to be easy to use with a simple API that gives back a clean object with the parsed results. If current docs or browser hints support matter, please include that too. Make sure it ships with good TypeScript support, sensible defaults, and a few examples in the README showing how to use it in real code.

Please also add tests for common browsers, phones, tablets, desktop OSes, bots, and a few weird user agents so the parser feels reliable. If you need to check current user agent formats or docs online, go ahead and look them up.
