 * FTS5 search across node titles + content.
 *
 * Uses an explicit bm25() with column weights 5.0 (title) and 1.0 (content)
 * so literal-token matches in the title rank above equally-literal matches
 * in the body — the common case when a user types a note name. We negate
 * bm25's output (lower-is-better) so SearchResult.score stays
 * higher-is-better, matching the semantic-search convention.
