zhuyongxin 584639fa2a docs(mvp): move engineering notes under mvp/engineering

Relocate RAG and diagnosis decision/E2E writeups from docs/ root into
mvp/engineering so architecture, issues, and engineering narrative stay
together. Update indexes and cross-links; leave docs/learning as legacy.

背景

lookup_knowledge 同文档多 chunk 在后处理与投影阶段被 source 级去重吞掉。Hybrid 多路召回前必须先修证据身份与裁剪契约。

按 evidenceKey 去重 + 每文档 chunk 上限
retrieve-k / return-n 分离
Projector 保留同 source 不同 chunk
薄 KnowledgeSearchPort，为 Delivery 2 hybrid 铺路

范围

Delivery 1 only（见 mvp/engineering/rag/Milvus-Hybrid接入清单.md §1.1）。

非目标

hybrid schema、BM25、删 SDK、session dedup、邻块重建、模型 rerank。
