 Run the worker as usual (`arq mymodule.WorkerSettings`) and enqueue jobs with only their real arguments, as in `await pool.enqueue_job("greet", "world")`. The `FromDI` parameters are resolved for you. A task must declare arq's `ctx` dict as its first parameter; injection is order-insensitive otherwise. arq's `ctx` is a plain `dict` (not a dedicated message type), so no context provider is registered. Read job metadata from `ctx`, and `fetch_di_container(ctx)` returns the root container.
