### Enhancements
- **Rope-based parsing**: Added direct rope parsing for FASTA, EMBL, and FASTQ formats via `FastaChunkParserRope`, `EmblChunkParserRope`, and `FastqChunkParserRope`. Sequence extraction now supports U→T conversion and improved line ending detection.
- **Rope scanner refactoring**: Unified rope scanning logic under a new `ropeScanner`, improving maintainability and consistency.
- **Sequence handling**: Added `TakeQualities()` method to BioSequence for more efficient quality data handling.
### Bug Fixes
- **Compression behavior**: Fixed `CompressStream` to correctly use the `compressed` variable instead of a hardcoded boolean.
- **String splitting**: Replaced ambiguous `SplitInTwo` calls with precise `LeftSplitInTwo` or `RightSplitInTwo`, and added dedicated right-split utility.
### Tooling & Workflow Improvements
- **Makefile enhancements**: Added colored terminal output, a `help` target for documenting all targets, and improved release workflow automation.
- **Release process**: Refactored `jjpush` into modular targets (`jjpush-notes`, `jjpush-push`, `jjpush-tag`), replaced `orla` with `aichat` for AI-assisted release notes, and introduced robust JSON parsing using Python. Release notes are now generated and stored in temp files for tag creation.
- **Versioning**: `bump-version` now supports the VERSION environment variable for manual version setting.
- **Submission**: Switched from raw `jj git push` to `stakk` for PR submission.
### Internal Notes
- Installation instructions are now included in release tags.
- Fixed-size carry buffer replaced with dynamic slice for arbitrarily long line support without extra allocations.
Add Jaccard distance and similarity computations for KmerSet and KmerSetGroup
This commit introduces Jaccard distance and similarity methods for KmerSet and KmerSetGroup.
For KmerSet:
- Added JaccardDistance method to compute the Jaccard distance between two KmerSets
- Added JaccardSimilarity method to compute the Jaccard similarity between two KmerSets
For KmerSetGroup:
- Added JaccardDistanceMatrix method to compute a pairwise Jaccard distance matrix
- Added JaccardSimilarityMatrix method to compute a pairwise Jaccard similarity matrix
Also includes:
- New DistMatrix implementation in pkg/obidist for storing and computing distance/similarity matrices
- Updated version handling with bump-version target in Makefile
- Added tests for all new methods
