## Summary

Deliver `@suaveplan/react-dialogue` on the genesis branch from scratch at enterprise quality. The package is the headless React layer around `@suaveplan/dialogue`. A `DialogueUIStateManager` wraps a `ConversationSession`; `useDialogue()` provides access via `useSyncExternalStore`; typed components display the current node text, speaker name, typewriter text animation, and choice buttons with condition-gated disabled state. Genesis adds Storybook stories, Vitest DOM tests, and 100% coverage.
