fix: rivetkit build (#4147)

# Description

This PR removes the unused `waitForNames` method from the `QueueManager` class and reorganizes imports across several files to improve code organization. It also fixes the Drizzle ORM exports by creating a new `sqlite-core.ts` file that re-exports specific functions from the Drizzle ORM package, rather than exporting everything directly.

Additionally, the PR updates the `createFileSystemOrMemoryDriver` function to accept an options object instead of separate parameters, making the API more flexible and consistent.
