Description

Currently the sdk import sqlite3 at module load time, even when users doesn't configure it. This causes the package to fail in environment where sqlite3 native bindings cannot compile.

Future Work : Current used sqlite package doesn't compile under environments like Bun. While this PR fixes the issue for users who doesn't need sqlite in their configuration , we still need a way to make sure it works in every envs.

Fixes #3882
