Koa Node Resolve Middleware

This Koa middleware dynamically rewrites Node.js bare module specifiers (e.g., `import { foo } from "stuff";`) into relative paths (e.g., `./node_modules/stuff/index.js`) on the fly, directly within HTML and JavaScript files served by the Koa server. It's specifically designed to facilitate modern JavaScript module development in browsers without requiring a separate build step, by resolving module paths using the same rules as Node.js `require()`. The package is currently in a pre-release state (version `1.0.0-pre.9`), indicating ongoing active development towards a stable `1.0.0` release, though no specific release cadence is published. Its key differentiator lies in its real-time, on-demand transformation capabilities, making it highly suitable for rapid iteration in development servers, integrated testing environments (such as those using Karma), and simple static file serving. However, it explicitly carries a significant caveat: it is *not* recommended for high-volume production use due to the inherent performance overhead associated with parsing and transforming HTML and JavaScript content on every request. This focus on development efficiency over production performance is a core design principle.
