mowdown: HTML, CSS, and JS Production Bundler

Mowdown is a lightweight, standalone JavaScript bundler designed for straightforward production preparation of web applications. Currently at version 2.2.2, it provides a minimal approach to consolidating and optimizing HTML, CSS, and JavaScript assets without requiring complex build configurations or a persistent local server process. The tool operates by scanning specified HTML files, identifying local CSS and JavaScript references (via `<link>` and `<script>` tags), and then concatenating, minifying, and optionally applying Babel transformations to these assets. Its primary differentiator is its simplicity and "no build step" philosophy, aiming to reduce developer overhead by working directly with existing HTML structures rather than introducing module systems or advanced optimizations like tree shaking or code splitting. It is suitable for projects where the build process needs to be minimal and predictable, especially for static sites or simple web applications. It operates purely as a Node.js utility.
