* fix: ensure the typescript definitions only export correct value types
In typescript there are two main types of "types" you can export, value types (class, const) and definition types (type, interface). The typescript compiler will let anything declared via const or class be used as a value. Unfortunately we were exporting a bunch of things (see the diff) as class/const when they weren't actually exported values. This lead to typescript being happy but the runtime throwing errors (not something we want).
This change passes "exported-in" context through our docs, to the parser and then to the definitions generator to ensure we only mark things as exported in the ts defs that we actually export.
