chore(showcase): mark shared-state-streaming unsupported for 11 non-LangGraph frameworks

Per team decision 2026-05-07: state-streaming only works on LangGraph variants. Move shared-state-streaming from features to not_supported_features for ag2, agno, claude-sdk-python, claude-sdk-typescript, crewai-crews, langroid, llamaindex, mastra, ms-agent-dotnet, ms-agent-python, pydantic-ai. Catalog regenerator now classifies these cells as unsupported, so the docs render the blue UnsupportedBox instead of yellow Missing snippet warnings.
