  2. 🚀 Higher-Kinded-J v0.1.7 is LIVE!

    We've packed this release with ergonomic features for more expressive & robust Java:

    ✨ Smarter Optics: @GenerateLenses now auto-creates with* methods for easy immutable updates on your records.
    🎯 Targeted Traversals: New Traversals.forMap(key) plus modify() & getAll() for precise map value handling.
    ✅ Powerful Error Accumulation: Validated is now an Applicative, using Semigroup to beautifully accumulate errors.
    🧮 Deeper Foundations: New Semigroup, Monoid, & Foldable interfaces bring category theory power to Java.
    ↔️ Enhanced Type Flexibility: Wildcards (? super, ? extends) improve compatibility for Functor, Applicative, Monad.

    All documented in the updated hkj-book!
