🧰 Changes

i was reading through this blog post, which pointed out that including docs in your node_modules is a generally good DX practice (for both LLMs and humans) that have rdme installed locally.

this PR ensures that our documentation is published to NPM!

🧬 QA & Testing

confirmed that it'll be included by running npm pack locally.
