Connect LiveReload Middleware

connect-livereload is a Connect/Express middleware designed to inject the LiveReload script directly into HTML responses. This eliminates the need for a browser extension, simplifying the development workflow by automatically reloading the browser upon file changes detected by companion tools like `grunt-contrib-watch`. The current stable version is 0.6.1, which was published approximately 7 years ago (December 2018), indicating that the package is largely unmaintained. Its primary differentiation is the server-side injection, which contrasts with client-side browser extensions. It does not, however, serve the `livereload.js` script itself, requiring another module (e.g., a LiveReload server like `node-livereload`) to provide it. Configuration options allow for specifying the LiveReload server port, ignoring certain file types (e.g., `.js`, `.css`), or customizing the HTML detection and injection rules.
