Huge Go v1.27 release probably warrants some updates

[g-lok]

There's been some big changes in Go v1.27 that probably deserve some review. I know nothing about this codebase, so I have no idea if the improvements to generics, interfaces, embedded structs, json v2 etc will have much (if any) impact or benefit for this project, but the glaring and obvious one that stands out to me is that there is now a native stdlib for UUIDs. The external github.com/google/uuid dependency is no longer required. I'll create an issue for this and see if I can help make a PR for it, but I don't have the time or the chops to review all the other stuff (although I think go fix now automatically does this for you). I dunno, I'll see what the diff shows and see if it changed anything scary looking. Still, something important for the maintainer to consider.
