The langgraph-python starter crashes on Railway because of a directory structure mismatch: agents were in agent/ with langgraph.json inside agent/, causing langgraph_cli to fail resolving module paths. Match the demo package's working layout: - Move agents from agent/ to src/agents/ (same as demo) - Put langgraph.json at project root (same as demo) - Point entrypoint at root langgraph.json instead of agent/langgraph.json - Templatize Dockerfile.python with AGENT_DIR and DOCKER_EXTRA_COPY vars - Skip langgraph.json path rewriting when agentDir matches agentSourceDir - Update tests to use framework agentDir instead of hardcoding "agent" Regenerate all 17 starters.
