fix: improper errored exit code propagation

[mrverdant13]

Is there an existing issue for this?

• I have searched the existing issues.

Version

3.0.1

Description

When a command is run for a set of packages with the exec option, if the command exits with a non-zero code, the melos CLI does not propagate the failure result with an errored exit code.

Steps to reproduce

1. In a mono-repo with at least two packages.
2. Create the melos.yaml file with the basic Melos setup.
3. Define the following script:

   should-fail:
     description: A script that should fail.
     run: dart run absent_file.dart
     exec:
       concurrency: 1
       failFast: true
     packageFilters:
       scope: "*"

4. Run melos run should-fail --no-select.

Expected behavior

When running melos run should-fail, Melos should stop the whole execution with an errored exit code.

Given that the absent_file.dart file does not exist, the actual Melos execution workflow is interrupted in the first package but Melos ends up printing a SUCCESS message.

I have the same issue. Would be good if this can be fixed.
It also happens on macOS.
