Feature or enhancement

Proposal:

The WASM demo in Tools/wasm was very useful for getting a Python REPL setup working in my web app.

It would be wonderful if that demo could be updated to work with the new Python 3.13 REPL (pyrepl).
I believe this would require a change to the way the file streams are handled (stdin specifically) though I'm not currently certain how to make that change.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

    Fixed for 3.14.0RC1 and newer.

    Exciting!

    I tried to build 3.14.0rc1 for Emscripten and ran into some issues: #137025. I fixed the first one (haven't opened a PR yet) but haven't figured out the second one yet.
