- Introduced AcJsonSerializer/AcJsonDeserializer in AyCode.Core.Serializers.Jsons, optimized for IId<T> reference and circular reference handling.
- Added AcJsonSerializerOptions/AcSerializerOptions for configurable reference handling and max depth.
- Implemented fast-path streaming (Utf8JsonReader/Writer) with fallback to DOM for reference scenarios.
- Added type metadata/property accessor caching for performance.
- Provided robust object/collection population with merge semantics for IId<T> collections.
- Added AcJsonDeserializationException for detailed error reporting.
- Implemented UnifiedMergeContractResolver for Newtonsoft.Json, supporting JsonNoMergeCollectionAttribute to control merge behavior.
- Added IdAwareCollectionMergeConverter<TItem, TId> for merging IId<T> collections by ID.
- Included helpers for ID extraction and semantic ID generation.
- Added DeepPopulateWithMerge extension for deep merging.
- Optimized with frozen dictionaries, pre-encoded property names, and context pooling.
- Ensured compatibility with both System.Text.Json and Newtonsoft.Json.
- Support preloaded string intern table in binary header for efficient string interning and reduced output size.
- Add HeaderFlag_StringInternTable to BinaryTypeCode and update serializer/deserializer to handle intern tables.
- Simplify string interning logic: always intern eligible strings, remove candidate tracking.
- Refactor property name table and buffer management for clarity and efficiency.
- Remove obsolete interning/property name methods from serializer context.
- Add new output methods (ToArray, WriteTo, DetachResult) for buffer/result handling.
- Introduce QuickBenchmark.cs with benchmarks comparing AcBinarySerializer (with/without interning), JSON, and MessagePack, including repeated string scenarios.
