ERR_UNSUPPORTED_ESM_URL_SCHEME when running npm (or pnpm) run +folder on Windows (Node v25)

[jsperry0807-rgb]

When creating a new KosmoJS project and running the +folder script on Windows, Node throws an ERR_UNSUPPORTED_ESM_URL_SCHEME error.
It appears to be related to Windows absolute paths (C:...) not being converted to file:// URLs before being passed to the ESM loader.

Steps to Reproduce:
npx kosmojs my-app
cd my-app
npm install
npm run +folder

Environment:
OS: Windows 11 Home
PNPM: v10.28.2
Node.js: v25.5.0
Package manager: npm
Installed via: npx kosmojs my-app

await import(packageFile, {
with: { type: "json" }
}).then((e) => e.default);

needs to be replaced with:

import { pathToFileURL } from "node:url";
await import(
pathToFileURL(packageFile).href,
{ with: { type: "json" } }
).then((e) => e.default);
