Transitions the index from MPHF slot-based to physical iteration-order indexing, aligning with the unitig layout. Introduces a streaming-only pipeline for k-mer iteration that adheres to memory constraints by avoiding full in-memory collections. Updates layer and sibling iterators to own an Arc clone of the file reader, making them Send + 'static and safe for concurrent use without borrowing the parent. Exposes batch and k-mer iterator types publicly while simplifying signature syntax with modern lifetime elision.
