Methods of Web objects held in untyped code (Request, Response, Headers,
ReadableStream, its reader, AbortSignal) answered member calls only by
static name, so a property read such as hono's `raw[key]()` or
`typeof req.json` saw undefined. A handle class now lists the methods its
invoke answers; a read returns one shared function per method that calls
invoke on its `this` and raises Node's ERR_INVALID_THIS TypeError (or a
rejected promise for the async operations) on another receiver. The in
operator sees the methods and the modeled properties.
