@langchain/langgraph-api@1.2.1 (pulled transitively by langgraph-cli) imports
STREAM_EVENTS_V3_MODES from @langchain/langgraph/web, which only exists in
1.3.0. The starter's overrides + agent dep were pinning langgraph to 1.2.9,
causing the agent container to crash on startup with a SyntaxError. Bump
the override and the direct pin to 1.3.0, and pin @langchain/langgraph-cli
in the npx invocations so future cross-package drift in the LangChain
ecosystem cannot silently re-break this starter.

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.
