Highlights

CREATE INDEX CONCURRENTLY: BM25 indexes now support concurrent index builds, allowing index creation without blocking writes.
WAND pivot selection: Multi-term queries use improved pivot selection for faster top-k retrieval, complementing the existing Block-Max WAND optimization.
Iterative index scans: Queries without an explicit LIMIT now use exponential backoff to avoid scanning the entire index upfront.
Progress reporting: CREATE INDEX now reports progress via pg_stat_progress_create_index, visible in standard Postgres monitoring tools.
Index scan statistics: BM25 index scans now report tuple and page counts via pg_stat counters (visible in pg_stat_user_indexes and EXPLAIN (ANALYZE, BUFFERS)).

Fixed BM25 scoring accuracy: block-max upper bounds now use minimum fieldnorm instead of average, preventing valid matches from being incorrectly skipped by BMW optimization.
Fixed implicit text <@> text operator resolution in DML subqueries (INSERT...SELECT, UPDATE...FROM, etc.).
Fixed to_bm25query() to reject index names that don't refer to a BM25 index.
