Make a Phlex component reactive: include Hibiki::Reactive for signals read as plain method calls, Hibiki::Phlex::Rerenderable so the same instance can render again, and wrap it in Hibiki::Phlex.render_effect to get fresh HTML on every signal change — transport-agnostic, the block decides where the HTML goes.

Run a hibiki signal graph per ActionCable connection: build it in subscribed, mutate it from channel actions (batched, confined to one worker thread), and let effects push re-rendered partials to the page through Turbo Streams.
