types: improve type exports

 This package is inlined into Global & Browser ESM builds of user-facing renderers (e.g. `@vue/runtime-dom`), but also published as a package that can be used standalone. The standalone build should not be used alongside a pre-bundled build of a user-facing renderer, as they will have different internal storage for reactivity connections. A user-facing renderer should re-export all APIs from this package.
 
+For full exposed APIs, see `src/index.ts`. You can also run `yarn build reactivity --types` from repo root, which will generate an API report at `temp/reactivity.api.md`.

 The implementation of this module is inspired by the following prior art in the JavaScript ecosystem:
