ZCryptoContext class abstract mixin

Provides cryptographic primitives and precomputed tables required for ZCash operations (e.g., Poseidon hash, Sinsemilla commitments, and domain-separated commitments).

⚠️ Expensive to instantiate: creating a DefaultZCryptoContext allocates internal tables and constants, so it should be created once and passed to any code that requires it, rather than recreated repeatedly.
