Testing CJS exports with unbuild

There are some edge cases with CJS exports that are not supported by unbuild. This is a test to see how unbuild handles these edge cases.

Check unjs/unbuild#475 for further details.

This repository using unbuild v3.1.0, using 3.2.0+ will not work since the dts files are wrongly generated for package-a, package-c and package-d: checkout wrong-cjs branch.

To check the output, run:

pnpm install

then

pnpm build && pnpm test:attw
