Tyler Slaton 59eb245a1c fix(showcase/langgraph-python): align e2e specs + QAs with current demos
The specs and QA markdowns had drifted from the demos they describe.
This commit brings every test contract into line with the actual demo
source — eliminating false-greens, false-fails, and stale assertions.

False-fail spec assertions (would fail every run):
- `agentic-chat.spec.ts` — rewrote from the old `change_background` /
  `weather-card` / `useAgentContext` flow that no longer exists. New
  spec exercises the vanilla `<CopilotChat>` + three suggestion pills
  contract the simplified demo actually exposes.
- `gen-ui-tool-based.spec.ts` — asserted on UI text ("Use the sidebar
  to generate charts", "Chart Generator") that doesn't exist; switched
  to suggestion-pill assertions and scoped the SVG check to inside the
  assistant-message bubble (was matching CopilotChat's send-button
  SVG).
- `agent-config.spec.ts` — asserted heading "Agent Config Object" but
  the demo has "Agent Config".
- `multimodal.spec.ts` — asserted a non-existent "Multimodal
  attachments" heading; switched to the `multimodal-demo-root` testid.
- `chat-slots.spec.ts` — asserted `[data-testid="custom-assistant-
  message"]` and the bare text "slot" — neither exists. The actual
  signal is `data-slot-label="MessageView.AssistantMessage"` from the
  SlotMarker wrapper.
- `reasoning-default.spec.ts` — asserted `[data-testid="copilot-
  reasoning-message"]` and `[data-message-role="reasoning"]`; neither
  is emitted by `CopilotChatReasoningMessage`. Switched to the text-
  based "Thinking…/Thought for…" header label.

False-green spec assertions (passed for the wrong reason):
- `shared-state-read.spec.ts` — was a complete false-green: asserted
  on "Sales Pipeline", "Total Pipeline", "Active Deals" but the demo
  has been a Recipe Editor for some time. Rewrote against the
  recipe-card / ingredients-container / instructions-container testids.
- 11 specs (agent-config, beautiful-chat, frontend-tools-async,
  gen-ui-tool-based, gen-ui-agent, gen-ui-interrupt, hitl-in-chat,
  hitl-in-app, multimodal, readonly-state-agent-context, voice) used
  `[data-role="assistant"]` to gate "agent responded" — but the v2
  react-core bundle never emits that attribute (it ships
  `data-testid="copilot-assistant-message"`). Mechanical sweep to the
  correct testid.
- Deleted `shared-state-write.spec.ts` (route consolidated into
  `shared-state-read-write` earlier on this branch — spec targeted a
  removed demo) and `renderer-selector.spec.ts` (asserted on a radio-
  pill UI that no longer exists; the four "Declarative UI" variants
  are now separate manifest demos).

QA drift:
- `qa/gen-ui-tool-based.md` documented a "Haiku Generator" demo with
  haiku-card / japanese-line / english-line / haiku-image testids — a
  demo that doesn't exist anywhere on this branch. Rewrote to match
  the chart-rendering demo's actual testids and pill prompts.
- `qa/chat-slots.md` referenced "Custom Slot" pill / "Welcome to the
  Slots demo" heading / "This welcome card is rendered via the
  welcomeScreen slot." body text — all of which the slot-wrappers
  refactor on this branch removed. Updated to match the
  `custom-welcome-message` sub-slot that's actually rendered. Also
  fixed max-w-4xl → max-w-5xl to match the page.
- `qa/shared-state-read.md` said default instruction is "Preheat oven
  to 350 F" but the source has "Preheat oven to 350°F (175°C)".
- `qa/agentic-chat.md` rewrote to match the simplified vanilla-chat
  demo (the previous QA documented `change_background` / `WeatherCard`
  flows that no longer exist).
- `qa/reasoning-default.md` cited `kind: "testing"` in feature-
  registry.json for the `reasoning-default` entry; the registry entry
  has no `kind` field. Rewrote without the false cross-file claim.
- Deleted 4 orphan QA files for demos that don't exist:
  `agentic-chat-reasoning.md`, `hitl.md`, `hitl-in-chat-booking.md`,
  `shared-state-write.md`.
- Renamed `qa/reasoning-default-render.md` → `qa/reasoning-default.md`
  to match the manifest cell name.

QA: Agentic Chat — LangGraph (Python)

The minimum-viable CopilotChat demo: vanilla <CopilotChat> wired to a neutral helpful-assistant agent, with three starter-prompt suggestions. No tools, no custom rendering — anything richer belongs in dedicated demos (frontend-tools, tool-rendering, hitl-in-chat, etc.).

Prerequisites

  • Demo is deployed and accessible
  • Agent backend is healthy (check /api/health)

Test Steps

1. Initial render

  • Navigate to /demos/agentic-chat
  • Verify the chat input renders with placeholder "Type a message..."
  • Verify all three suggestion pills are visible:
    • "Write a sonnet"
    • "Tell me a joke"
    • "Is 17 prime?"

2. Free-form chat

  • Type a basic message (e.g. "Say hello") and press Enter
  • Verify the assistant streams back a text response

3. Suggestion pills

  • Click the "Tell me a joke" pill
  • Verify the message is sent and the assistant streams back a joke

4. Multi-turn context

  • Send "My name is Alice."
  • Wait for the assistant response
  • Send "What name did I just give you?"
  • Verify the assistant's second response contains "Alice"

5. Hygiene

  • No console errors during normal usage
  • No layout breakage with a very long input

Expected Results

  • Chat input mounts within ~3 seconds
  • Assistant first-token latency is under ~5 seconds for short prompts; full responses complete within ~30 seconds
  • Suggestion pills render alongside an empty chat and disappear once a conversation is in progress
