QA: BYOC (json-render) — CrewAI (Crews)

• Navigate to /demos/byoc-json-render.
• Verify the page root (data-testid="byoc-json-render-root") renders.
• Verify the composer shows the pre-seeded suggestion pills.
• Click a suggestion that exercises multi-component output (sales dashboard with metric + chart); verify the MetricCard renders WITH a nested BarChart below it (children forwarding works).
• Click a pie-chart suggestion; verify the PieChart renders without a React console error like "useVisibility must be used within a VisibilityProvider" (JSONUIProvider must wrap Renderer).
• Click a bar-chart suggestion; verify the BarChart renders with correctly-labelled bars.
• Verify that, while the agent is mid-stream, the default assistant message bubble shows the streaming text; once the JSON is complete, the view switches to the rendered components.
