Describe the feature you'd like to request

In the canonical example, turbo run dev --parallel --no-cache is used for development.

However, --parallel will build dependent tasks in parallel too, even though those might need to be executed in dependency order.

Given a graph like: A -> B and A -> C

And a turborepo definition like:

    "turbo": {                                                                                                                                                                                                                  
        "pipeline": {
            "build": {
                "dependsOn": ["^build"]
            },
            "dev": {
                "dependsOn": ["build"]
                "cache": false
            }
        }
    }

Running turbo run dev --parallel --no-cache will break on the build step, because the builds of B and C depend on the build of A completing.

Describe the solution you'd like

One possible solution is to add a parameter like --parallel-depth=1 (default: Infinite), where only the dev commands are executed in parallel, but deeper dependent commands are not.

Describe alternatives you've considered

Removing build from dev: { dependsOn }, and executing 2 commands works:

turbo run build
turbo run dev --parallel --no-cache
