- Fixed master key loading from MASTER_KEYS environment variable to preserve usable key material by copying decoded bytes before zeroing temporary decode buffers
- Hardened MasterKeyChain.Close() to explicitly zero all in-memory master keys before clearing chain state, preventing potential memory leaks
- Added regression test coverage for key usability after load and secure zeroing during close
- Updated all documentation and examples to reference v0.5.1 release
- Added comprehensive release notes (docs/releases/v0.5.1.md) and upgrade guide (docs/releases/v0.5.1-upgrade.md) with verification commands
- Updated compatibility matrix with v0.5.0 -> v0.5.1 patch upgrade path
- Updated CHANGELOG.md with security fixes and documentation improvements
