v0.0.1.dev3

HieraChain Engine v0.0.1.dev3 - ZK Proof Security Layer

Pre-release Warning: This is a development preview and is not intended for production use. APIs may change without notice.

What's New

This release focuses on Zero-Knowledge Proof (ZK) and developer experience improvements. Key changes include adding ZK proof fields to Block and Transaction schemas for trustless verification between SubChain and MainChain, improved debug logging for Arrow stream processing, and codebase organization improvements.

ZK Proof Support

• Block Schema ZK Fields: Added zk_proof and zk_public_inputs binary fields to Block schema for SubChain → MainChain trustless verification (b463200).
• Transaction Schema ZK Fields: Extended Transaction schema with zk_proof and zk_public_inputs fields for per-transaction proof attachment (b463200).

Developer Experience

• Arrow Handler Debug Logging: Added detailed debug output showing received batch dimensions (rows/cols) and first column preview for easier troubleshooting (1856db4).
• Improved Error Handling: Error checking moved before record processing in Arrow stream handling for clearer error messages (1856db4).

Maintenance

• Schema File Renaming: Renamed schema.go → schemas.go and schema_test.go → schemas_test.go for naming consistency (acf5636).
• Rust FFI Library Path: Updated build flags with correct library path for Rust FFI integration (50b383b).
