Fix: DOM types (#172)

Fixes:

- Node: A couple of type errors which were mistakenly introduced when excluding global DOM types

- Web: Node types were mistakenly being included by `tsconfig.web.json`, as well as `src/dom/index.ts` (which wasn't actually in use, it was a naive first attempt at setting up aliasing for each target's DOM implementation)
