Support for AI browsers

[ineffyble]

We're starting to see users with AI browsers such as Comet and ChatGPT Atlas. They're all Chromium based but because they store data in their own paths, Aftermath doesn't collect them currently.

Will try and make a PR for this next week unless @attacus-tw beats me to it.

I started with Comet because it was fairly straightforward.

Atlas's file structure is a bit more complex. The path used for user profiles in Atlas is {homedir}/Library/Application Support/com.openai.atlas/browser-data/host/user-{id}__{uuid}, but there is a lot of other data in this file structure that malware might grab. I'm not yet familiar enough with how Atlas works to get a sense of what else might need to be supported, but implementing a Chrome-like parity is doable.

Dia Browser is another one that's starting to get some traction. Aftermath supports Arc, by the same developers, but I haven't yet had the time to look into whether that translates to easy Dia support.
