Concise way to depend on scripts in child and dependency workspaces

[aomarks]

[1] Run <script> in all of my workspaces (parent → child).

With Wireit, you can already just do npm run build -ws to run a given script in all workspaces, which is the standard npm workspaces approach. However it's not fully optimal, because npm doesn't parallelize. So we will also support a syntax like this:

{
  "name": "root",
  "scripts": {
    "build": "wireit"
  },
  "wireit": {
    "build": {
      "dependencies": [
        {
          "script": "build",
          "packages": "workspaces"
        }
      ]
    }
  },
  "workspaces": [
    "packages/foo",
    "packages/bar"
  ]
}

Which is equivalent to:

{
  "name": "root",
  "scripts": {
    "build": "wireit"
  },
  "wireit": {
    "build": {
      "dependencies": {
        [
          "./packages/foo:build",
          "./packages/bar:build"
        ]
      }
    }
  }
}

[2] Run <script> in all of my dependencies (child → siblings).

Related, it is often useful to run some script in all of the current packages dependencies (where those dependencies are workspaces contained by the same workspace root).

{
  "name": "foo",
  "scripts": {
    "build": "wireit"
  },
  "wireit": {
    "build": {
      "dependencies": [
        {
          "script": "build",
          "packages": "dependencies"
        }
      ]
    }
  },
  "dependencies": {
    "bar",
    "baz"
  }
}

Which is equivalent to:

{
  "name": "foo",
  "scripts": {
    "build": "wireit"
  },
  "wireit": {
    "build": {
      "dependencies": [
        "../bar:build",
        "../baz:build"
      ]
    }
  }
}

I'm faking this in the interim by adding this to the root package.json

{
  "private": true,
  "workspaces": [
    "packages/*"
  ],
  "scripts": {
    "build": "wireit"
  },
  "wireit": {
    "build": {
      "dependencies": [
        "./packages/core:build",
        "./packages/preact:build"
      ]
    }
  },

where core and preact are the folder names of my local packages. Now I can, e.g. yarn run build watch and have all my packages transitively watched without running into serial blocking issues.

IMO, I hope it can be set like turborepo's dependsOn.
If packages.json has workspaces or file pnpm-workspaces.yaml exists, it can be recognized as a workspace.

{
  "scripts": {
    "build": "wireit",
    "lint": "wireit",
    "test": "wiret",
    "test:all": "wiret"  // Root only
  },
  "wireit": {
    "build": {
      "dependencies": ["^build"]
    },
    "lint": {
     },
    "test": {
     "dependencies": ["build"]
    },
    "test:all": {
      "dependencies": ["lint", "test"]
    }
  },
  "workspaces": [
    "packages/foo",
    "packages/bar"
  ]
}

What would "^build" in a dependency mean?
