[New] add TypeScript types

[G-Rath]

For now I've just typed these out manually based on what we're using internally - while it would be good to have some tests at some point, I'm hoping/recommending not blocking on that for now as I think the types are small enough to be easy to maintain manually for the time being.

Resolves #3090

Can we add a tsc run, at least?

Can we add a tsc run, at least?

Done - note that it requires using typescript v5 since types like @types/node require that version, which led to a weird "works locally but not in CI", but I think I've got that resolved and should be good enough for now 🤞

I'll merge this without verifications in place, but it'll be very very important to add that soon.

@ljharb would you mind to get this published on npmjs.com, please? The latest version 2.31.0 still doesn't have this change.
