dev: repl stuff (#337)

* dev: nrepl: allow interrupts

https://docs.cider.mx/cider/basics/up_and_running.html#enabling-nrepl-jvmti-agent

* dev: optionally enable flowstorm support for repl

Flowstorm is a wonderful develpment diagnostic tool.

Don't think this will work for when bringing up a cljs repl via `bb
dev-cljs`, but am happy with only clj repl (via `bb dev-clj`) support
for now.
