 - `hook` installs behavior at an OpenCode extension point.
 - `reload` reruns every transform hook for a stateful domain.
 
-The only difference from the Effect API is the async boundary: hook callbacks, hook registration, `reload`, and `Registration.dispose` use Promises instead of Effects.
+The Promise API uses Promises instead of Effects for setup, runtime hook
+callbacks, hook registration, `reload`, and `Registration.dispose`. Transform
