You want to create a new package for this called node-embed-sdk. embed-sdk interacts with the frontend

Thank you, I pretty much just copied the project structure over from embed-sdk to make this new one.

NIce! I think you also need a CHANGELOG.md file and a changeset or this using pnpm run changeset

EDIT: just checked my previous PRs / commits, you only need a changeset

I think that adding a net-new package would qualify as a minor, not major, change since no existing APIs have changed, so I went ahead and added a minor changeset
