Pull request overview

This PR bumps the version from 0.1.15 to 0.1.16 and includes important improvements to the sharding architecture and documentation. The key change is refactoring ShardsMap to use an instance-level RandomState hasher instead of creating a new FixedState on each shard lookup, which improves hash consistency. Documentation has been significantly enhanced with new caveats about lock poisoning behavior and performance characteristics.

• Refactored ShardsMap to use an instance-level RandomState hasher for consistent key-to-shard mapping
• Added comprehensive documentation about lock poisoning, performance considerations, and usage patterns
• Enhanced README with expanded feature descriptions, caveats, and improved code examples
