node-pty dependency breaks running Phoenix in browser

[AtkinsSJ]

Running Phoenix in the browser now fails because of the node-pty dependency added for the PathCommandProvider. This causes us to include a binary file, which the rollup common-js plugin gets very upset about.

We don't need or want that included, since PathCommandProvider only works when running in the Node CLI. However, excluding source files from rollup is less straightforward than I'd hoped and I'm not sure what I'm doing. 😅

We can prevent the code including that with this change:

diff --git a/src/puter-shell/main.js b/src/puter-shell/main.js

 const argparser_registry = {
     [SimpleArgParser.name]: SimpleArgParser

...however, rollup can't tell that this (or whatever other check) doesn't include PathCommandProvider.js, so it adds it anyway.

A temporary workaround is to not include it at all:
