storyblok/monoblok ? reverse-engineered prompt

Build me a Storyblok JavaScript monorepo that keeps all the official SDKs and framework integrations in one place. I want it set up so each package can be developed, tested, and published independently, but still shares the same repo workflow and tooling.

It should include the core JavaScript client, the CLI, the region helper, and the framework packages for React, Vue, Nuxt, Svelte, Astro, and the rich text renderer. Make the experience clean for contributors, with good docs, easy local setup, and sensible scripts for linting, testing, and releasing.

If anything is unclear from the current docs, look up the latest Storyblok package patterns online and match the existing ecosystem as closely as possible.
