DCRYPT v0.6.0: Type-Driven Architecture Redesign

A complete reimagining of the DCRYPT cryptography library architecture focused on:

• Type-level validation with const generics for guaranteed correctness
• Zero-cost abstractions that compile to the same code as raw alternatives
• Builder pattern with fluent interfaces for all cryptographic operations
• Comprehensive trait hierarchy mirroring cryptographic primitive concepts
• Context-preserving error handling with detailed validation
• Progressive disclosure - simple tasks remain simple while complex ones become possible

This major release prioritizes compile-time safety over runtime checks, making cryptographic misuse nearly impossible through the type system while maintaining an intuitive and ergonomic developer experience.
