The node module main file is the `"main"` key in your package.json file, and defines the entrypoint for your library when consumed as a node library, and must reference a js file. The TypeSpec main defines the entrypoint for your library when consumed from a TypeSpec program, and may reference either a js file (when your library doesn't contain any typespec types) or a TypeSpec file.
