FastWire: Add markerless string encoding/decoding
Introduced a markerless FastWire path for string properties and collection elements in AcBinary serialization. Strings are now encoded with a 4-byte int32 sentinel header (-1=null, 0=empty, N>0=content) and UTF-16 bytes, eliminating the type code marker in FastWire mode. Updated code generation, runtime, and documentation to support this, while preserving Compact mode behavior and cross-mode compatibility.
.NET 9 core framework providing serialization (Binary, JSON, Toon), entity abstractions, database access, services, and shared utilities. Used as the foundation layer for AyCode applications.
