Update Vector Graph RAG with two-stage Jev evaluation

[zc277584121]

Vector Graph RAG now uses two-stage Jev relation selection and full-passage reranking. Its evaluation covers 1,000 MuSiQue and 1,000 2Wiki queries, reaching 76.78% and 95.35% Recall@5 respectively (86.07% average).

The project reports its strongest retrieval results among the compared baselines. The linked report includes saved results, reproduction scripts, and the quality–latency comparison.

Evaluation: https://github.com/zilliztech/vector-graph-rag/blob/main/evaluation/jev/two-stage/README.md

I am a contributor to Vector Graph RAG and work on search at Zilliz.

Replaces the earlier 500-query relation-only evaluation entry with the full two-stage evaluation. The entry qualifies the Pareto-frontier claim with the report's reference latency estimates.

Passes the Primary test: this is a direct Jev evaluation with public results and reproduction scripts.

Validation: lint and all 15 count checks passed; git diff --check passed. The evaluation URL is directly accessible.

Hi @unikcc, thanks for merging our earlier evaluation entry. This update replaces the 500-query relation-only results with the new two-stage Jev evaluation: 1,000 queries each on MuSiQue and 2Wiki, averaging 86.07% Recall@5. It links the full report and its quality–latency comparison. Lint, counts, and the new link check passed. Would appreciate your review when convenient!
