Clone isn't necessary (clippy should whine about this, if it isn't we've probably got it set up wrong).

Indeed, Clippy wasn't complaining. Something was apparently misconfigured, I can't figure what.
I got it working by adding clippy directives at the top of lib.rs, but I see no other of our project does that. Suggestions?

I believe this works, but it's really hard to be sure.
Another option, that I thiiiink works, is to use a mutex that protects both things. The only situation you need to deal with is having the JS call not happen under the lock - but that's easy, because it's already in an Arc. So, just clone it under the lock and then call it outside of it. We already accept that double-calls are fine.
That might make it a lot easier to reason about.

WIP - Just ignore for now
What changed
Major refactor of Core bridge.
Removed reactor event loop on Runtime and Worker; relying on Tokio's event loop. This greatly simplify the bridge code.
Use Neon's Deferred/Promise support rather than callback functions +
promisifyon the TS side.Split code to files.
Overall, align TS' bridge with how we do things in other Core-based SDKs. That should make it easier to port features across Core-based SDKs in the future.
Fix some runtime-initialization hack related to metrics setup, which was in the way of implementing custom metrics support.
