Release v3.5.4

Features

• Source generator now supports excluding members by visibility.
• Added FastClonerVisibilityAttribute to control member visibility handling at the type level for both runtime and source-generator paths.
• Added FastClonerStableHashAttribute to improve stable hash detection for cloner caching.
• Introduced NonPublicAccessorEmitter and BridgeProxyEmitter in the source generator to enable safe access to non-public members without reflection at runtime.
• Added FastClonerSourceGeneratorBridge and associated contract attributes to support tighter integration between the runtime cloner and source-generated cloners.

Fixes

• Fixed a race condition in the cloner state management.
• Fixed cloning of private and protected fields in source-generated cloners.
• Resolved an edge case that could cause incorrect cloning behaviour in certain type graphs.
• Improved cycle tracking to correctly handle complex object graphs.
• Improved stable hash detection to reduce false cache misses.
• Fixed nullability warnings across the codebase.

Chores

• Updated README with revised documentation and usage guidance.
• Expanded test coverage with new test classes covering bridge proxy emission, non-public accessor generation, struct boxing via the runtime bridge, visibility attribute behaviour, and source generator edge cases.
