Benjamin Taylor 501565c966 fix(examples): green parity + starter smoke — v2 label keys, llamaindex v2 state, parity sync
Addresses the blocking review on #5151:

1. Starter smoke 'Popup Assistant' timeouts (adk, agno, mastra,
   ms-agent-framework-python/dotnet): the pages passed the dead v1 label keys
   (labels.title / labels.initial), which v2 CopilotSidebar ignores — the
   header rendered the default 'CopilotKit Chat' so the smoke's
   text=Popup Assistant wait timed out. Map to the v2 CopilotChatLabels keys:
   title -> modalHeaderTitle, initial -> welcomeMessageText. Verified live:
   SSR now renders 'Popup Assistant'.

2. llamaindex TypeError (reading 'proverbs'): the page still used the v1
   useAgent API ({ state, setState } = useAgent({ name, initialState })) —
   v2 returns { agent }, so state was undefined at render. Migrate to the v2
   pattern (agent.state with a guarded default + agent.setState + one-time
   seed effect), and fix its dead v1 label keys too. Verified: next build
   prerenders all pages cleanly.

3. parity-check drift: ran _parity/sync.ts --all — syncs example-layout
   (mobile-header fix), layout.tsx, docker-route-override.ts to the
   north-star, and bumps @copilotkit/* to 1.59.1 in langgraph-fastapi and
   strands-python. parity verify: 0 errors across all instances.
   (next-env.d.ts is gitignored repo-wide; verify warns-and-skips it in a
   clean checkout, so it is intentionally not committed.)

4. Trailing-whitespace diff-check failure (showcase google-adk agent): already
   resolved by the merge of main (the file matches main; diff --check clean).

/**

* In Docker, the agent is served via AG-UI (not LangGraph Platform)
* because langgraph-cli dev requires Docker-in-Docker.
* The original route.ts (using LangGraphAgent) is preserved unchanged.
