Jordan Ritter d6b784ee9a feat(showcase): add interrupt demos to 12 integrations via Strategy B
Replace gen-ui-interrupt and interrupt-headless "not supported" stubs
with working demos using useFrontendTool + async Promise pattern.
Backend agents use system prompt + tools=[] — CopilotKit runtime
routes tool calls to the frontend handler. Pattern proven by
ms-agent-python/dotnet, now extended to ag2, agno, built-in-agent,
claude-sdk-python, claude-sdk-typescript, crewai-crews, google-adk,
langroid, llamaindex, mastra, pydantic-ai, strands.
