New example app demonstrating the OpenUI artifact system for displaying
AI-generated code in a resizable side panel.

* feat: add Artifact() factory function in react-ui, migrate artifact demo

Adds Artifact() to @openuidev/react-ui — a factory that returns a
ComponentRenderer with automatic useId, useArtifact, and ArtifactPanel
wiring. Consumers provide preview/panel render functions; no manual
artifact boilerplate needed. No changes to lang-core or react-lang.

- react-ui: new Artifact() function with ArtifactControls injection
- example: migrate ArtifactCodeBlock to use Artifact()
- example: remove artifactId from schema and prompt, simplify InlinePreview
