Lage doesn't run root level dependency target when without specified `type`

Describe the bug
Lage doesn't run root level dependency target when without specified type: "npmScript".

To Reproduce

Code:

// root package.json
  "scripts": {
    "lage": "lage",
    "touch-foo": "touch foo.js"
  },

// lage.config.js
  pipeline: {
    "#touch-foo": [],
    lint: ["#touch-foo"],

Running lage --verbose --no-cache lint outputs:

<root> touch-foo ➔ start
<root>touch-foo ✓ done - 0.14s

But foo.js is never created. It works when I add an explicit type: "npmScript"

Expected behavior
Target should have a default type npmScript or just fail with a clear error message.

Environment/Troubleshooting
Please paste in the result of npx envinfo to help identify your run time environment

If this is an issue with run order of tasks, please paste in the result of lage info [your command(s)] [options]

Reproduce the behavior with the root package.json and lage.config.js shown in the report, using lage --verbose --no-cache lint. Trace how the root #touch-foo target is interpreted when its type is omitted, then verify that the target either runs as an npmScript or reports a clear error, including the creation of foo.js.
