Claim root dev dependencies in linked test resolution

Composer installs the root package's require-dev alongside require, and
the ../* path repository shadows any sibling on Packagist. cli's dev
dependency on console resolved fine until console was absorbed; then the
path repo offered it as dev-main, unclaimed, failing the 0.0.* constraint.
