Rails 7 E109 Live vistor count. ActionCable, Turbo Broadcasts, Kredis

Let's add "Live count for total website visitors" and "Live count for visitors inside a room".

Importantly, we will not deal with user REGISTRATION to identify a visitor. One browser session = one unique visitor with a session_id.

We will use "turbo_stream_from" to plug into an ActionCable Channel and track websocket subscriptions and un-subscriptions.
Whenever a user "subscribes", we will add his browser session_id to a Kredis array.
We will Broadcast the updated Kredis array COUNT to everybody subscribed to the channel.

Sounds quite complex, but I still think of it as a very low-code solution.
