refactor: move RAG trace classes to argtrace package and update SQL schema

- Rename org.ruoyi.trace package to org.ruoyi.argtrace for RagTraceNodeTypes
  and RagTracePayloadBuilder; fix package declarations and update imports in
  ChatServiceFacade and KnowledgeRetrievalServiceImpl
- Remove obsolete RagTracePayloadBuilderTest
- Switch supervisor response strategy from SUMMARY to LAST in ChatServiceFacade
- Refresh docs/script/sql/ruoyi-ai.sql with the latest full schema dump
- Add live demo links (admin panel, user frontend, commercial edition) to
  README.md and README_ZH.md
