What is the problem this feature would solve?

Eliding is a useful tool when running multiple projects in union, however it has been proven somewhat cumbersome in our case when the filter is applied to only one project. Imagine a folder structure like this:

- package.json
o webapp
  - package.json
o backend
  - package.json

having a package.json in the root with scripts like

{
  "scripts": {
    "dev": "bun run --filter '*' dev",
    "dev:webapp": "bun run --filter 'webapp' dev",
    "dev:backend": "bun run --filter 'backend' dev",
  },
  "workspaces": ["backend", "webapp"]
}

causes eliding on commands like bun run dev:webapp and bun run dev:backend where it's not necessary to keep an overview of the terminal output.

What is the feature you are proposing to solve the problem?

This would restore regular bun run output when only one project is being run, as if it was transparently running the other projects without workspaces.

What alternatives have you considered?
