Adds hitl-in-app, readonly-state-agent-context, auth, agent-config, voice, multimodal, byoc-hashbrown, and byoc-json-render demos to the built-in-agent showcase. Each demo lives under src/app/demos/<feature> with a dedicated runtime route under src/app/api/copilotkit-<feature> where required. Patterns: - hitl-in-app and readonly-state-agent-context are frontend-only and reuse the default /api/copilotkit runtime. - auth uses createCopilotRuntimeHandler with the V2 onRequest hook to reject requests missing the Bearer token. - agent-config reads input.forwardedProps inside the BuiltInAgent factory and prepends a tone/expertise/length-tuned system prompt. - voice mounts at [[...slug]]/route.ts and registers TranscriptionServiceOpenAI from @copilotkit/voice; falls back to a 401 with 'api key missing' when OPENAI_API_KEY is unset. - multimodal reuses the base gpt-4o factory (vision-capable) and the TanStack converter (convertInputToTanStackAI) for native image and document part forwarding — no langgraph-specific binary rewrite. - byoc-hashbrown and byoc-json-render add per-demo factories that pin modelOptions.response_format to json_object so the streaming UI parsers receive a single valid JSON object with no preamble.
