Describe the Bug

Observed behavior

Tests fail when using runInDurableObject() when package.json contains a namespace in the name field (e.g. @repo/worker-a instead of worker-a.)

Note: adding a namespace like @repo/ to packages is useful in monorepos for tools like syncpack where I want to treat all @repo/ packages as local.

Expected behavior

Tests pass

Steps to reproduce

git clone https://github.com/jahands/cf-vitest-pkg-name-error.git
cd cf-vitest-pkg-name-error
pnpm install
pnpm test
