fix(rpc): favour zod types only

[kyranjamie]

Figuring out best way to handle some message passing and continually running into need to runtime check a payload & narrow the type. This is only possible if all method requests and response are available as schemas. I regret setting up this type structure and not going validator first from the start.

I know we don't follow the convention of "section comments" like I've used here, but find schema heavy files hard to navigate without.

There's a pretty crazy type overload here. The tricky part is that some methods do / do not have params defined. And, based on whether or not a params schema is defined, the inferred type should know whether or not there's a params object. I tried using a conditional type e.g. TParams extends undefined ? X : Y but it didn't infer correctly.
