refactor: replace mutex with channels for parallel debruijn processing

Add `rayon` and `crossbeam-channel` dependencies to support concurrent execution. Replace the synchronous, mutex-protected closure pattern with a channel-based producer-consumer approach using `std::thread::scope`. This decouples unitig iteration from processing, eliminating lock contention and `Mutex` overhead while enabling parallel workloads.
