"""Worker entrypoint: runs trigger checker + future background jobs.

Waits for the database (and required tables) to be ready before starting
the background loops. This prevents the worker from crashing when the
backend hasn't finished running `init_db()` yet (typical docker-compose
race condition where both services start in parallel).
