Reproduction steps

pnpm --no-bail --aggregate-output --reporter=append-only --workspace-concurrency=0 run '/^lint:/'

package.json:

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "lint:a": "sh -c 'for i in {1..30}; do echo foo; sleep 0.1; done'",
    "lint:b": "sh -c 'for i in {1..30}; do echo bar; sleep 0.1; done'"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

Describe the Bug

--aggregate-output currently only works for scripts across workspaces, but not for scripts within the same workspace.

The reproduction leads to:

. lint:a$ sh -c 'for i in {1..30}; do echo foo; sleep 0.1; done'
. lint:b$ sh -c 'for i in {1..30}; do echo bar; sleep 0.1; done'
. lint:a: foo
. lint:b: bar
. lint:a: foo
. lint:b: bar
. lint:a: foo
. lint:b: bar
. lint:a: foo
. lint:b: bar
. lint:a: foo
. lint:b: bar
. lint:a: foo
. lint:b: bar
. lint:a: foo
. lint:b: bar
. lint:b: bar
. lint:a: foo
. lint:b: bar
. lint:a: foo
. lint:b: bar
. lint:a: foo
. lint:b: bar

Expected Behavior

I would have expected for the tests inside the same workspace to also have aggregated output.
