First-class delegation for intent handlers.
Compose with AppleIntents.Intent to set delegated_task/0 and
require_approval?/0 without boilerplate:
defmodule MyApp.PhotoIntent do
use AppleIntents.Intent, intent: "OrganizePhotos"
use AppleIntents.Delegated, task: "organize_photos", require_approval: true
endWhen delegated_task/0 is non-nil, AppleIntents.Router routes work through
AppleIntents.Orchestration instead of calling handle/2.
