refactor: handle kmer deduplication and layer initialization concurrently

Browse Source 
Introduce a secondary layer iteration to open `SrcLayerData` alongside the unitig reader for concurrent metadata access. This refactors the merge routine to handle kmer deduplication and per-layer data initialization simultaneously. Also corrects a typo in `rebuild_layer.rs` where `openopen_sequential` is renamed to `open_sequential`.
