Tyler Slaton ebad989855 chore(showcase/langgraph-python): manifest, runtime, e2e, cleanup
Cross-cutting changes that don't belong with any one demo: manifest +
landing-page tags, runtime route adjustments, e2e + QA notes that
follow the demo renames, and a few small cleanups.

Manifest (manifest.yaml + src/app/page.tsx tag labels):
- Naming convention: every demo uses `Thing: Subthing` (Generative UI:
  Tool Rendering - Default / Custom Default / Specific; Open Generative
  UI: Default / Advanced; Shared State: Streaming / Read + Write;
  Reasoning: Default / Custom; Frontend Tools: In-App Actions / Async;
  Human in the Loop: In-chat / In-App / Interrupt based; Chat
  Customization: CSS / Slots; Headless UI: Simple / Complete).
- Retags: Auth → `platform`; HITL Step Selection + Interrupt-based →
  `interactivity`; Reasoning Default + Custom → `chat-ui`; Generative
  UI: Tools → `generative-ui`.
- Renames: Readonly State (Agent Context) → Frontend Context Sharing.
- HITL slot points at /demos/hitl-in-chat (working
  useHumanInTheLoop+interrupt path) instead of the previous
  /demos/hitl that had no backend `interrupt()` calls.
- Highlight paths corrected for the rebuilt headless demos (root-level
  paths replaced with hooks/, chat/, tools/, attachments/ subdirs).
- Descriptions rewritten where they had drifted from the implementation
  (gen-ui-agent: dropped useCoAgentStateRender claim;
  headless-simple: shadcn primitives, not raw Tailwind;
  headless-complete: enumerates the actual hooks wired).

Runtime / route:
- src/app/api/copilotkit/route.ts — 30 agents registered (incl. the
  reasoning-custom rename from agentic-chat-reasoning).
- copilotkit-mcp-apps/route.ts replaced with [[...slug]]/route.ts so v2
  subpath POSTs (/v2/agent/run) resolve.
- src/app/api/copilotkit-voice/[[...slug]]/route.ts — env var standardized
  (was `AGENT_URL || LANGGRAPH_DEPLOYMENT_URL`, now matches the rest
  of the showcase with just LANGGRAPH_DEPLOYMENT_URL); trailing `/`
  removed from deploymentUrl.

Tests / QA:
- e2e specs renamed and paths updated for the demo renames.
- qa notes for a2ui-fixed-schema (booked-state checklist removed) and
  byoc-json-render (Wave 4a residue removed).
- docs-links.json key renamed for reasoning-custom.

Cleanup:
- Removed remaining stub agent.py files in demo dirs (real graphs in
  src/agents/); removed dead beautiful-chat/components/headless-chat.tsx
  (zero importers); removed [A2UI-DEBUG] / [A2UI-RESPONSE] print
  statements from beautiful_chat.py; gpt-5.4-mini → gpt-5-mini typo
  fix in beautiful_chat.py:249 (would have 4xx'd every model call);
  stripped iframe-restriction LLM-prompt copy bleed from
  open-gen-ui-advanced suggestion titles.

The convention pass that ran across ~28 demos earlier in this branch is
already reflected in their per-demo commits — every page.tsx reads as
imports + provider + suggestions hook + JSX, with `useConfigureSuggestions`
extracted to a sibling suggestions.ts.

QA: BYOC json-render — LangGraph (Python)

Prerequisites

  • Demo deployed at /demos/byoc-json-render.
  • Railway backend healthy (showcase-langgraph-python-production.up.railway.app).
  • OPENAI_API_KEY and LANGGRAPH_DEPLOYMENT_URL configured on the Next.js app.
  • @json-render/core + @json-render/react present in package.json (pinned to 0.18.0).
  • byoc_json_render graph registered in langgraph.json.

Test Steps

1. Page load

  • Navigate to /demos/byoc-json-render.
  • Chat composer is visible.
  • Three suggestion pills appear with titles: "Sales dashboard", "Revenue by category", "Expense trend".
  • No console errors.

2. Sales dashboard suggestion

  • Click the "Sales dashboard" suggestion.
  • Within 60 seconds, a data-testid="json-render-root" wrapper appears in the assistant bubble.
  • A data-testid="metric-card" renders inside the wrapper.
  • A chart (data-testid="bar-chart" or data-testid="pie-chart") renders inside the wrapper.
  • No raw JSON text is shown once rendering finishes — the streaming JSON is replaced by components.

3. Revenue by category

  • Click the "Revenue by category" suggestion.
  • Within 60 seconds, a data-testid="pie-chart" renders with multiple category slices + legend.

4. Expense trend

  • Click the "Expense trend" suggestion.
  • Within 60 seconds, a data-testid="bar-chart" renders with month labels.

5. Free-form prompt

  • Type "Show me a metric for quarterly revenue" and send.
  • Verify at least one metric-card renders; no console errors.

6. Multi-turn

  • After a previous render is visible, send a follow-up prompt ("Now break that down by region").
  • A new assistant message appears with a new json-render rendering — prior renders stay in the transcript.

7. Malformed output handling

  • If the agent ever replies with non-JSON text (force it by asking "tell me a joke"), the chat falls back to rendering that raw text via the default assistant bubble. No crash, no stuck spinner.

Expected Results

  • Suggestion renders land within 60 seconds. Budget is slightly higher than the hashbrown demo because a JSON { root, elements } spec is more verbose than hashbrown's token stream.
  • No uncaught errors in the console.
  • Streaming falls back to plain text until the JSON parses, then swaps to rendered components.
