Research direction
The bug occurs when running `yarn add` in a workspace package that depends on a local workspace package. The error shows it's trying to fetch from the registry instead of resolving locally. Look at the reproduction repository at https://github.com/aymericbeaumet/yarn workspace add package.git. Investigate the workspace resolution logic in Yarn's source code, particularly how `yarn add` handles local dependencies in workspaces. Focus on the package resolution in the `src/` directory. The issue has extensive comments; check if any maintainer has pointed to specific files.
