Refactor k-mer matching to use a pipeline architecture with improved concurrency and memory management: - Replace sort.Slice with slices.SortFunc and cmp.Compare for better performance - Introduce PreparedQueries struct to encapsulate query buckets with metadata - Implement MergeQueries function to merge query buckets from multiple batches - Rewrite MatchBatch to use pre-allocated results and mutexes instead of map-based accumulation - Add seek optimization in matchPartition to reduce linear scanning - Refactor match command to use a multi-stage pipeline with proper batching and merging - Add index directory option for match command - Improve parallel processing of sequence batches This refactoring improves performance by reducing memory allocations, optimizing k-mer lookup, and implementing a more efficient pipeline for large-scale k-mer matching operations.
