🚀 Zvec v0.5.1 Release Notes

External Vector Source: Added support for using external vector sources, enabling more flexible data ingestion and retrieval workflows. (#490)
Zero-Copy Vector Query Path: Added VectorViewClause to support a zero-copy query path and unified vector query validation. (#478)
Search Prefetch Configuration: Added support for passing prefetch configuration (PO and PL) through search parameters. (#482)
Index Dirty Status: Exposed is_dirty through the core Index interface so callers can inspect whether an index has pending changes. (#488)

Parquet Buffer Cache: Refactored parquet buffer cache ownership to avoid lifetime and ownership issues. (#492)
