-- echo_emitter.lua
-- Echo component for ChannelRunner mode (uses orcs.output for output).
--
-- This script demonstrates ChannelRunner-based execution where output
-- is emitted via events instead of directly to IO.
--
-- Usage:
--   let component = ScriptLoader::load_embedded("echo_emitter")?;
--   engine.spawn_runner_with_emitter(channel_id, Box::new(component));
