wip: enable nested optimization

[dominikg]

• reorganized test dependencies and added cjs/esm deps

Tests are failing for pnpm test:ci:build because tests where simple-svelte dependency is used , cjs-only is added to build output without cjs to esm transform.

Tests fail on windows because somehow the importAnalysis plugin does not replace the cjs import in Dependency.svelte of the svelte-simple test dependency.

This works on linux and mac, so my guess is that the /@fs prefix on windows is not accounted for correctly in https://github.com/vitejs/vite/blob/c6896e80699bc05791ff1ba6ba665bc683181c28/packages/vite/src/node/plugins/resolve.ts#L482 which leads to an import url that doesn't have the &es-interop marker appended and then the import is not replaced with the optimized version.

:/
