[bug\_fix] Error: Cannot find module '@scope/shared-utils' Require stack: /path/to/packages/app/index.js

Explicitly add the workspace package as a dependency in the consuming package's package.json using the workspace protocol \(e.g., "@scope/shared-utils": "workspace:\*"\), then run pnpm install from the monorepo root.

Journey Context:
Developer sets up a monorepo using pnpm workspaces. They create packages/app and packages/shared-utils. In app, they try to import '@myorg/shared-utils'. They run the app and get 'Cannot find module'. They check node\_modules and see a symlink exists to the shared-utils folder. They check the code and the export exists. They try using pnpm -r run build. The error persists. They search and find that pnpm uses a strict node\_modules structure with content-addressable storage. Unlike npm/yarn, pnpm enforces that workspace dependencies must be explicitly declared in package.json to be resolvable, and the workspace: protocol ensures the correct linking. They realize they manually created the folder but forgot to add "@myorg/shared-utils": "workspace:\*" to packages/app/package.json. After adding it and running pnpm install, the symlink is properly registered in pnpm's virtual store, and the module resolves correctly.
