Add wiki_partial indices: BM25, SPLADE++, BGE, Contriever, Qwen3-Embedding-4B
Adds prebuilt indexes over the **partial Wikipedia corpus** (`wiki_partial.jsonl`, 5,910,177 passages) under `indices/wiki_partial/`, next to `e5_partial/`. Index files only (no embedding memmaps).
| Folder | Retriever | Settings |
|---|---|---|
| `bm25_partial/` | BM25 (Lucene) | positions, doc vectors and raw docs stored |
| `spladepp_partial/` | SPLADE++ `naver/splade-cocondenser-ensembledistil` | Lucene impact index, max_length 256 |
| `bge_partial/` | `BAAI/bge-large-en-v1.5` | FAISS Flat, CLS pooling, max_length 512, d=1024 |
| `contriever_partial/` | `facebook/contriever-msmarco` | FAISS Flat, mean pooling, max_length 512, d=768 |
| `qwen3_emb_4b_partial/` | `Qwen/Qwen3-Embedding-4B` | FAISS Flat, last-token pooling, max_length 512, d=2560; **2 parts**, `cat qwen3_emb_4b_Flat.index.part_* > qwen3_emb_4b_Flat.index` |
