Reconstruct Original HTTP Request URL

The `original-url` package provides a utility function to reconstruct the full, original URL of an HTTP request by intelligently parsing various standard and de-facto standard HTTP headers. It accounts for potential modifications made by proxies, load balancers, and other intermediaries by examining headers like `Host`, `Forwarded`, `X-Forwarded-Proto`, `X-Forwarded-Host`, `X-Forwarded-Port`, and others. If the protocol cannot be determined from headers, it leverages the TLS connection's `encrypted` flag. The module returns a URL object compatible with Node.js's native `url.parse` output, including a `full` property for the complete URL string. The current stable version is 1.2.3, published over 6 years ago, indicating a very mature or slow-moving project that is likely in maintenance mode rather than active development. Its primary differentiator is its comprehensive handling of various proxy-related headers to accurately determine the client-facing URL.
