Exokit Studio debugging documentation

From exokitxr/exokit#955

Perhaps a better solution than documenting this smorgusbord of debuggers is delivering a better debugging solution in the studio, as well as a remote debugger for the mobiles.

One is the user debugging their JS. This is probably most important, and would be expected to be used by HTML/JS code authors, including framework authors. This is a concern for the studio. The documentation extent of this would be how to use it in the studio.
