Add `indicatif` v0.17 to `obikmer` and `obikpartitionner` to instrument CLI workflows with real-time progress tracking. The changes integrate progress spinners and bars into the batch processing and parallel kmer counting loops, displaying processed base pairs, throughput rates, and elapsed time. Updates occur every 0.1s to enhance observability without modifying core partitioning logic.
Replace in-memory hashing with a disk-backed external merge sort and `PersistentCompactIntVec` to drastically reduce peak RAM. Unify both phases using a custom `PtrHash` MPHF, eliminating `GOFunction` and `boomphf`. Introduce a concrete three-step `count_partition()` pipeline with adaptive chunk sizing based on available system memory. Update dependencies to `memmap2`, `ptr_hash`, and `obicompactvec`. Additionally, document strict genomics-only memory constraints and enforce an architectural feedback workflow requiring explicit user authorization before structural changes.
Introduce the `obilayeredmap` specification and persistent MPHF-based index architecture for incremental multi-dataset indexing. Implement chunked binary serialization with a fixed `u8` k-mer count limit (256) and overlapping super-kmer segments. Add memory-mapped I/O and a companion `.idx` index file for allocation-free, O(1) unitig access. Update MkDocs navigation, enhance the k-mer comparison script, and add comprehensive tests for serialization, partitioning, and file I/O pipelines.
