AcBinarySourceGenerator now reads feature flags from [AcBinarySerializable], enabling selective code generation for ID tracking, reference handling, and string interning. Property ordering is always alphabetical, removing "Id"-first sorting for IId types. Reference tracking code is only emitted when features are enabled. TypeMetadataBase and AcBinarySerializer runtime logic now respect these flags. Default options updated: ReferenceHandlingMode is All, UseMetadata is false. Test models explicitly disable all features. Comments and code structure improved for clarity.

- Fix: Ensure property names and skipped strings are interned during binary deserialization, preventing interned string index mismatches.
- Add: Extensive regression tests for string interning edge cases, including property mismatch (server has more properties than client), deeply nested objects, repeated/unique strings, and empty/null handling.
- Add: New test DTOs and infrastructure for property mismatch scenarios.

- Improve: SignalRRequestModelPool now initializes models on Get().

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.
