A one-command demo server for the fake-Slack dev UI.
Slackbox.Demo.start/1 boots a self-contained supervision tree (PubSub, the
in-memory Slackbox.Store, and a Phoenix endpoint serving
Slackbox.DashboardLive), seeds a few messages, and prints the URL. Push more
messages live from IEx with Slackbox.Demo.post/2 and watch them appear.
