Add regression tests for string-stored DateTime values in GenericAttribute-like collections, ensuring exact value preservation in Binary serialization. Fix AcBinaryDeserializer to only intern strings >= 4 chars, matching serializer logic and preventing intern table index mismatches. Refactor SignalR tests to run under both JSON and Binary modes, and add comprehensive tests for edge cases and production bug scenarios. Clean up test code and comments for clarity.
Major overhaul of binary serialization:
- Rewrote AcBinarySerializer as a static, optimized, feature-rich serializer with VarInt encoding, string interning, property name tables, reference handling, and optional metadata.
- Added AcBinaryDeserializer with matching features, including merge/populate support and robust error handling.
- Introduced AcBinarySerializerOptions and AcSerializerOptions base class for unified serializer configuration (JSON/binary).
- Added generic extension methods for "any" serialization/deserialization based on options.
- Updated tests and benchmarks for new APIs; fixed null byte code and added DateTimeKind test.
- Fixed namespace typos and improved code style and documentation.
- Introduce AcBinarySerializerTests with full coverage for primitives, objects, collections, merge/populate, and size comparisons
- Add AcBinarySerializer class stub as a placeholder for implementation
- Extend serialization extension methods with binary helpers (ToBinary, BinaryTo, BinaryCloneTo, etc.)
- Update test models to ignore parent references for all major serializers ([IgnoreMember], [BsonIgnore])
- Refactor benchmarks: split into minimal, simple, complex, and MessagePack comparison; add command-line switches and improved size reporting
- Optimize AcJsonDeserializer with fast UTF-8 property lookup and direct primitive setting
- Add MessagePack and MongoDB.Bson dependencies to test and benchmark projects
- Add (accidentally) a summary of less commands as a documentation artifact
