v0.7.0

Minor Changes

• fe0e69f: Three ingestion/retrieval capabilities: xlsx parsing with header-repeating markdown row groups (chunker-friendly tables, section = sheet name), image/png + image/jpeg support with an exported captionImage vision bridge (cached, jpeg re-encode, defensive downscale), and graphRecall — an opt-in entity-match third recall source fused into hybrid search via N-way RRF (absent hook keeps retrieval byte-identical). Benchmark gains graph on/off A/B configs.
