cljs.repl is not loaded in node socket io-prepl, which is required for formatting errors (err->str)

Question

Mike introduced a change to improve spec failure output in this commit: https://github.com/clojure/clojurescript/commit/59997385d85e7e1af1559d599eb51fdb1d7e93b1#diff-cba27ef5577ebe459e904b894c982c0bR89

This code depends on cljs.repl being loaded, this is not the case by default in a ClojureScript socket based io-prepl. If an error is thrown it will instead throw again because it can't find cljs.repl/err->str (the name will appear munged in the JavaScript stacktrace).

Should we ensure cljs.repl is loaded within this node prepl context? I'm also wondering why only node_repl.js exists, why isn't the same error handling included for browser / graal / nashorn REPLs? Maybe it is and I'm just missing something.

For the error handling in other REPLs CLJS-3011.
