Nodes created via some paths store configuration under "config" instead of
"data", causing agent/LLM/orchestrator nodes to run with default settings
(gpt-4o-mini/openai instead of the configured model). This caused 橙子 agent
scheduled tasks to fail with "节点 node-agent-1 执行失败: 未知错误".
Add normalize at execute_node entry + fallback reads in agent/LLM/orchestrator
handlers.
