Don't build CJS for pretest or while watching (#6820)

It's important that when we're doing a full build for distribution (eg,
`postinstall`) that we build both CJS and ESM. But when we're just doing
development, building for both outputs just wastes CPU and makes errors
show up twice.

So in the places designed for development (the `pretest` script and the
VSCode watch task), link in the ESM versions of dual-build projects (as
well as all test suites).

Also, align `npm run watch` with the VSCode watch task (ie, make it
watch tests too).
