• Replaces atomic int64 variables with atomic.NewInt64() constructors
• Updates atomic operations to use the new method-based API

@SuperQ They're not enabled by default - I tend to request them myself, just to catch in case I make some stupid mistake. I can stop requesting them if you don't like them :)

I'd like to disable it completely. It's not reliable. It's more I now need to look at when reviewing a PR.

"AI" is not ready for this kind of work.
