Export toWebRequest(req, parsedBody?, options?) — the Node IncomingMessage → web-standard Request conversion toNodeHandler already performs internally. Use it to feed isLegacyRequest() (or handler.fetch()) from a hand-wired Node/Express (req, res) handler instead of assembling a globalThis.Request from req.headers by hand. When a body parser already consumed the Node stream (express.json()), pass the parsed value as parsedBody; pass options.signal to tie the constructed request to client disconnect, the way toNodeHandler does.
