SQLite IndexedDB Benchmark - Full Comparison

# SQLite IndexedDB Performance Benchmark

Comparing: AbsurderSQL (persistent SQLite + IndexedDB VFS), absurd-sql (persistent SQLite + IndexedDB), and raw IndexedDB
All implementations use persistent IndexedDB storage. AbsurderSQL uses our optimized BlockStorage (20x faster reads!).
NOTE: Each benchmark run now cleans up IndexedDB completely to ensure consistent performance between runs.
