Shifts sibling annex construction from slot-indexed enumeration to iteration-order traversal by correcting cumulative k-mer offset tracking in batch enumeration. Replaces coarse per-partition parallelism with chunked work distribution to prevent thread starvation on skewed partitions. Decouples custom progress messages from ETA updates to eliminate display clobbering during high-frequency callbacks. Adds regression tests validating batch offset correctness, partial batch handling, and iterator-order consistency across layer builds.
