Chris Tate a57089aebf Accept readline's dispose, instanceof, dynamic streams and non-string prompts ...

rl[Symbol.dispose]() closes the interface, as Node's dispose method
calls close(). rl instanceof readline.Interface and
readlinePromises.Interface answer which module created the interface:
rl.create's mode marks readline/promises interfaces, and the fallback
declarations declare both Interface classes as values.

In JavaScript, createInterface's input and output can be checked-dynamic
values (a function's result, an object's member, an element that may be
undefined): rl.inputFromDyn and rl.outputFromDyn unbox the stream they
hold, an output of null or undefined means no output, and other values
are refused.

In JavaScript, question() and setPrompt() accept a value that is not a
string. When such a prompt is written, an interface that is not a
terminal throws ERR_INVALID_ARG_TYPE as Node's kWriteToOutput does, and
the readline/promises question rejects with it; the question stays
pending and the previous prompt returns when it is answered. A terminal
interface writes String(value) of a primitive.

Corpus 5876-5878 match Node v24.22.0.
