[BUG] workspace scripts do not propagate exit codes

[JamesHenry]

Is there an existing issue for this?

• [X] I have searched the existing issues

This issue exists in the latest npm version

• [X] I am using the latest npm

Minimal Setup

package.json

{
  "workspaces": ["child"],
  "scripts": {
    "exit-100": "exit 100"
  }
}

child/package.json

{
  "scripts": {
    "exit-100": "exit 100"
  }
}

Repro Steps

Behavior in root:

npm run exit-100
echo $? # correctly returns 100

Behavior in workspace:

npm run exit-100 --workspace child
echo $? # incorrectly returns 1

# OR

cd child
npm run exit-100
echo $? # incorrectly returns 1

Also note, if you amend the root package.json to remove the workspaces and then repeat those final steps:

cd child
npm run exit-100
echo $? # (now without workspaces config in the level above) correctly returns 100

Environment

• npm: 9.5.0
• Node.js: 18.15.0
• OS Name: macOS 13.3.1

I have a minimal reproduction repo here as well: https://github.com/mehulkar/turbo-issue-5098 with node 20.2 + npm 9.6.

@mehulkar my guess is you are actually running into https://github.com/npm/cli/issues/6399 and not what I am describing here
