Module pool 

Connection pool for SQLite.

This module provides an optimized connection pool for SQLite databases. Unlike PostgreSQL/MySQL, SQLite has unique characteristics:

• In-memory databases: Each connection has its own isolated database
• File-based databases: Connections share the same database file

For file-based databases, this pool reuses connections to avoid the overhead of opening new connections (~200µs per open).
