- Add BINARY_FORMAT.md: full AcBinary wire format spec (markers, encoding, options, protocol, interactions)
- Reference BINARY_FORMAT.md from GLOSSARY.md, Binaries/README.md, and Serializers/Binaries/README.md; add new glossary terms
- Clarify and expand config options tables to match new doc
- Add/clarify LLM maintenance rules: always sync .md files with code, auto-fix discrepancies
- Update root README.md: AyCode.Core targets .NET 9, not 10; stress doc/code sync
- Add code reuse and doc sync conventions to copilot-instructions.md and CONVENTIONS.md
- Add docs/ folder and BINARY_FORMAT.md to solution as Solution Items
- Minor clarifications and cross-links in ARCHITECTURE.md and other docs
Added comprehensive README.md documentation to every project and subfolder in the solution. Each README describes the purpose, key files, structure, dependencies, and design patterns for its area. This improves codebase navigability and maintainability, and includes a maintenance note to keep docs in sync with future code changes.
- Updated all projects to use `Newtonsoft.Json` v13.0.3 for consistency.
- Introduced `HybridReferenceResolver` for semantic and numeric ID handling.
- Refactored `SerializeObjectExtensions` to support deep JSON merging.
- Simplified `IId<T>` interface by removing `IEquatable<T>` constraint.
- Improved `AcSignalRDataSource` with robust `AddRange` and `CopyTo` methods.
- Added `JsonExtensionTests` for deep hierarchy, reference, and edge cases.
- Implemented `UnifiedMergeContractResolver` for custom JSON behavior.
- Optimized type/property caching with `TypeCache` and `CachedPropertyInfo`.
- Enhanced SignalR integration to fix primitive array deserialization issues.
- Introduced `JsonNoMergeCollection` attribute for replace-only collections.
- Added test DTOs and `TestDataFactory` for real-world scenario simulations.
- Improved performance with `ConcurrentDictionary` and `ObjectPool`.
- Fixed `$id`/`$ref` handling for non-semantic references and arrays.
