Michelle0474 0fc72a9474 Add Qwen2.5-7B MolRAG encoder branch + dual-seed results ...

- llm_prompt.py: RAG prompt encoding (use_rag), Qwen support, set_retrieval_pool (leak-safe, train-only pool)
- models.py: use_rag/rag_top_k passthrough to LLMPromptEncoder
- nested_cv_optuna.py: --use-rag CLI, per-fold retrieval pool (防泄漏), slim checkpoint (skip frozen LLM weights)
- Qwen+RAG results: seed42 delivery R2=0.2151, seed123=0.1558 (mean 0.185), best LLM encoder so far
