-Add CIP-30 message signing support with modular architecture
-
-This release introduces comprehensive CIP-30 `signData` and `verifyData` support, implementing the complete COSE Sign1 specification with a clean, modular structure:
-
-**New Features:**
-- Full CIP-30 message signing (`signData`) and verification (`verifyData`) implementation
-- COSE (CBOR Object Signing and Encryption) primitives per RFC 8152
-- Support for Ed25519 signatures with proper COSE key structures
-- Message hashing with BLAKE2b-256 for payload integrity
-- CIP-8 compliant address field handling
-- Complete test coverage with CSL compatibility tests
-
-**Module Structure:**
-- `message-signing/SignData.ts` - Main CIP-30 signData/verifyData API
-- `message-signing/Header.ts` - COSE header structures and operations
-- `message-signing/Label.ts` - COSE label types and algorithm identifiers
-- `message-signing/CoseSign1.ts` - COSE_Sign1 structure implementation
-- `message-signing/CoseKey.ts` - COSE key format support
-- `message-signing/Ed25519Key.ts` - Ed25519 key operations
-- `message-signing/Utils.ts` - Encoding and conversion utilities
-
-**Breaking Changes:**
-- Refactored `Bytes` module API:
-  - Renamed `bytesEquals` to `equals` with stricter type signature (no longer accepts undefined)
-  - Removed `Bytes.FromHex` schema in favor of Effect's built-in `Schema.Uint8ArrayFromHex`
-  - Updated `fromHex`/`toHex` to use Effect's native schemas
-
-**Internal Improvements:**
-- Removed unused `Bytes` imports across 32 files
-- Updated all modules to use new Bytes API
-- Improved CBOR encoding/decoding with proper codec options
-- Enhanced type safety with Effect Schema compositions
