Updates the obikmer lockfile version to 1.2.1 and configures the obikindex dependency to explicitly disable default features. These are manifest and lockfile adjustments that do not modify source code or alter application behavior.
Adds a new binary that validates bit-level consistency between dense and sparse K-mer index representations by sampling slots across partitions and reporting discrepancies. Refactors sibling cache matrix initialization into a centralized factory method to simplify control flow and standardize error handling. Introduces diagnostic configurations, benchmark scripts, and an ignored test case to support k-mer resolution analysis.
