#408 Batch symbol lookup in RRF fusion #410
Description
Problem
After RRF fusion, each result calls get_symbol_by_id(conn, id) individually -- N+1 query pattern. 20 results = 20 SQL queries.
Location
src/index/brain.rs:132-147
Solution
Replace N individual SELECT ... WHERE id = ?1 with a single SELECT ... WHERE id IN (?, ?, ...).
Expected Impact
Eliminate 20+ queries per search.
