Bring the starter agents' Python dependency pins (pyproject.toml + uv.lock
for adk, langgraph-fastapi, langgraph-python, pydantic-ai, strands-python;
requirements.txt + docker override for crewai-crews) in line with the
showcase fleet pin standard.
The build-starters Docker images hardcoded copilotkit==0.1.78 in the
langgraph-python and langgraph-fastapi Dockerfiles, but their agents import
StateStreamingMiddleware and StateItem, which 0.1.78 does not export. This
crash-loops the Python agent on boot with an ImportError. Bump the hardcoded
pin to 0.1.93 (latest stable, re-exports both symbols, matches local
sdk-python). Align all three langgraph-family agent pyproject pins
(0.1.87 -> 0.1.93) for consistency and regenerate the strands uv.lock.
Flatten langgraph-python, langgraph-js, and mcp-apps starters so
npm install && npm run dev works out of the box. Replace Turborepo
with concurrently, move apps/* to root, update Dockerfiles, READMEs,
and entrypoints. Also remove stray pnpm-lock.yaml from a2a-a2ui and
ms-agent-framework-dotnet starters.
