- Add `Chunk` to split slices into groups of size n. - Add `ContainsBy` for predicate-based containment checks. - Add `UniqueBy` to deduplicate slices by key selector. - Add `ParallelMap` for concurrent mapping with context and error handling. - Add `maps.Keys` and `maps.Values` helpers for extracting map keys/values. - Update README and docs for new features. - Refactor `Contains` to use `slices.Contains`.
