This release introduces support for zero-copy deserialization via the rkyv framework. It enables the dictionary to be mapped into memory and queried directly without allocations or data movement.

Key Changes:

• rkyv Integration: Added rkyv::Archive, Serialize, and Deserialize traits to Dict and KeysContainer (optional via rkyv feature flag).
• Zero-copy Lookups: Implemented get and contains for ArchivedDict, allowing lookups directly on serialized byte buffers or mmaps.
• Miri Validation: Verified pointer arithmetic in archived lookups to ensure no undefined behavior (UB) during relative offset resolution.
• Performance: Standard in-memory operations remain unaffected. Archived lookups use scalar probing to maintain safety and cache density.

Usage:
