chore: some suggestions for repo setup

[rflechtner]

Generally looking good to me, what the different functions are for is not immediately obvious to me, so I'll stick to general things:

• When using the yarn version plugin we can upgrade to yarn version 4 which has promoted that plugin to a builtin
• We could maybe just use the tsconfig.json as the base, reducing the number of files
• On the topic of release strategies: I'd recommend using a deferred version bump (you want a patch release rn, if I got that right) on a feature branch, and then running yarn version apply and committing as part of the actual release on the main branch. That's how we have it set up for the jcs repo for example.
• If you want to export types separately from the root (their already included in star exports anyway) it's probably better to not re-export function declarations as well; so in the types.ts files you'd have to do selective exports of types instead.
