Alem Tuzlak 9e54ba6706 fix(showcase/google-adk): beautiful-chat icon, calculator, hitl, voice mic, state-context gating
Production-fix bundle for beautiful-chat + 3 other google-adk demos. All
issues either reported on Railway prod or unmasked by the catch-all
render_a2ui fallback I added in #4836. Local D5 stays 38/38 green.

- Missing copilotkit logo: `<img src="/copilotkit-logo-mark.svg">` returned
  404 because the SVG never shipped in the integration's public/. Copy
  copilotkit-logo-mark.svg + copilotkit-logo.svg over from langgraph-python.

- Multimodal sample.png / sample.pdf were LFS pointers in prod (Railway
  build runs without `git lfs pull`), so the magic-byte check rejected them
  on first click. Add an integration-scoped .gitattributes that exempts
  these two paths from LFS (mirrors what every working sibling integration
  already does) and re-stage the files as real binaries (10KB / 2.5KB).

- Sales Dashboard pill returned a generic "Step 1... Step 2..." narration
  instead of rendering the A2UI surface. Root cause: the render_a2ui
  catch-all fallback I added to aimock/d5-all.json in #4836 fired before
  feature-parity.json's specific sales-dashboard fixture (load order
  d5-all → smoke → feature-parity). Removing the catch-all from both
  d5-all.json and the per-demo source so the specific fixture wins.

- Calculator App pill returned text only with a white iframe because
  beautiful-chat's agent instruction never mentioned generateSandboxedUi —
  Gemini saw the tool listed via AGUIToolset but had no nudge to use it.
  Added a one-line "Interactive / sandboxed widgets" entry to the
  instruction; verified Gemini now emits the tool call.

- hitl-in-app refund (#12345) and escalate (#12347) pills broke on the
  second click because the 2nd-turn fixtures keyed on `sequenceIndex` 0/1
  (a global thread-position counter that drifts when other pills land
  tool messages in the same thread). Convert both to `toolCallId +
  hasToolResult: true` and drop the reject branch — Gemini reasons
  correctly from the tool's `approved: false` return without a fixture
  override. Same pattern that fixed tool-rendering-reasoning-chain
  previously.

- hitl-in-app downgrade (#12346) pill produced an unrelated
  "Research / Outline / Draft / Review / Finalize" plan because the
  prompt contains the substring "plan" and feature-parity.json has a
  generic catch-all match on `userMessage: "plan"`. Add a specific
  downgrade fixture in d5-all.json (loaded before feature-parity.json)
  with hasToolResult: false / true branches.

- hitl-in-chat "Schedule a 1:1 with Alice" returned the wrong
  "Nice to meet you, Alice in Tokyo" response when clicked AFTER another
  pill in the same thread. The 2nd-turn fixture only matched on
  `toolCallId` (no hasToolResult), so the bare "alice" / "Alice" greeting
  fixtures further down won. Add `hasToolResult: true` to the 2nd-turn
  fixture so it scopes correctly regardless of thread state.

- Voice manual recordings always returned "What is the weather in Tokyo?"
  regardless of audio content. aimock had a catch-all transcription fixture
  (`match: { endpoint: "transcription" }`) that returned the canned
  Tokyo string for any audio input. The D5 voice probe uses the sample
  audio button which bypasses /transcribe entirely (it injects text
  directly into the composer), so removing the transcription fixture
  drops aimock into --proxy-only fall-through to real OpenAI Whisper for
  mic recordings while D5 stays green. Verified.

- readonly-state-agent-context and shared-state-read-write fixtures
  returned hardcoded "Atai" / generic preferences responses even when
  the user changed the state values in the UI inputs. Gate the
  Who-am-I / Suggest-next-steps / Greet / Plan-a-weekend fixtures on
  systemMessage substring matching the canonical default state values
  ("Atai" name for readonly-state-context; "tone: casual" for
  shared-state-read-write). When the user changes state, the agent's
  before-model callback rebuilds the system prompt with the new values,
  the fixture's systemMessage substring no longer matches, and aimock
  --proxy-only falls through to the real model so the response reflects
  the actual state. Confirmed with paired curl tests (default state =
  fixture match; alem name = real-LLM response).

Local verification: bin/showcase test google-adk --d5 finishes 38/38
green (137s). Calculator pill confirmed via direct ADK invocation
against real Gemini (GOOGLE_GEMINI_BASE_URL=) emits TOOL_CALL_START
toolCallName=generateSandboxedUi. Sales-dashboard pill confirmed end-to-end
returning the full Column / DashboardCards / PieChart / BarChart payload.
readonly-state-context confirmed with name=Atai matching fixture vs
name=alem falling through to real-LLM response that uses the actual
context.
