Pull request overview

This PR updates the Rust worker execution loop to take advantage of BullMQ’s moveToFinished “fetch next job” capability, reducing per-job Redis roundtrips by chaining directly into the next job when available. It also ensures worker-level rate limiting remains enforced when chaining by including limiter options in the packed moveToFinished opts.

Changes:

• Add limiter to moveToFinished packed options so fetchNext honors rate limiting.
• Allow move_to_finished_fast / job completion & failure handlers to return an optionally fetched next Job.
• Update the worker loop to process chained jobs in a tight loop using the same token, avoiding extra moveToActive calls.
