npm in a scratchpad: install without leaving JSLab

We make JSLab, a JavaScript and TypeScript scratchpad for Mac, so this is show-and-tell, not a review.

The video shows JSLab's package sheet.

Press ⌘I, search the registry as you type and click Add, or type name@version and press Return. Packages install into one project that every tab shares, so a package you add in one tab is available in the others straight away, without restarting.

Import something you don't have yet and JSLab offers to install it:

// dayjs isn't installed yet: click Install on the error row, or the lightbulb on line 2.
import dayjs from "dayjs";
dayjs().format("dddd, MMMM D");

Once the install finishes, the tab runs again by itself, and the editor picks up the package's types.
