⚡ Bolt: [performance improvement] Optimize SQLite insertions by replacing execute with executemany in _record_user_decision (#234)

Eliminates an N+1 performance bottleneck during batch file processing by grouping user feedback into a single `executemany` database insertion. Avoids executing repeated SQL parsing and reduces Python-to-C API crossover overhead, speeding up processing for large file groups.
