Live Templates: connect a template in HTML to a stateful back end

The live-template element provides a connected, or "live" template that connects to a stateful backend application provided by Livestate. After connecting to a LiveState channel, it will

- render the initial state - subscribe to state updates and re-render on changes - push events to a Livestate channel which may then compute a new state

If you squint really hard, you can think of it as HTMX meets Elixir ;)
