Updated CI workflow cache keys with a `v2` salt and `Cargo.lock` hash to prevent stale incremental compilation caches and deadlocks, while updating restore keys and documenting interrupted job state. Introduced a 3-way ordinal distance metric framework that replaces ambiguous IUPAC encoding with explicit k-mer scoring, bridging pairwise methods to character-based phylogenetics via Sankoff parsimony. Bumped the `obikmer` crate version to 1.1.42.
