/**
 * Scan-mode full-text search — ranks **already-decrypted** records by
 * BM25 against a tokenized query. Pure client-side: nothing is written to the
 * store, so this adds **zero** leakage (unlike a store-usable blind index,
 * which is a separate, gated opt-in).
 *
 * O(n) over the collection; intended for small/medium collections (the pilot's
 * scale) where moving the existing userland scan into the DB is the win.
