Thanks @lin-stephanie!
This plugin looks really good.
It's great that testing, types, and lint checks area already in place.

Some subtle, non-blocking thoughts:

1. @types/hast is included in the distributed/production types, it could be good to move it to a dependency (rather then devDependency) to ensure stricter package managers like yarn/pnpm are happy using it https://github.com/lin-stephanie/rehype-callouts/blob/a48cda574d01d6b931d954f93fec36e0517675d8/package.json#L53
2. It looks like publishing is done through a GitHub action, it could be good to include provenance information to allow adopters to trace the release back to a specific build https://github.blog/security/supply-chain-security/introducing-npm-package-provenance/, though it might take some tinkering to get that to work with pnpm Pnpm publish with provenance flag doesn't work pnpm/pnpm#6607
