⬆️ refactor superkmer to use obipipeline
- Replace manual threading with Pipeline abstraction from `obipipline`
- Remove crossbeam-channel dependency and format detection logic
- Introduce typed `PipelineData` enum for pipeline stages (RawChunk, Norm Chunk, Batch)
- Implement shared normalization and extraction steps as `SharedFn`ƒ
- Add unsafe Send/Sync impls for PipelineData (Rope ownership is moved, not shared)
- Replace manual reader/worker/output threads with a single Pipeline execution
- Uses `make_source_fallible!`, shared transform functions, and a sink for output
- Simplify argument handling (remove `--format` flag)
- Update Cargo.toml: remove crossbeam-channel, add obipipeline
