refactor: implement binary parsing in L0 DataTable rows

- Add BinaryReaderExtension with Vector2/3/4, Quaternion, Color, Rect types
- Implement ParseDataRow(byte[]) in TagRow and RarityTagBudgetRow
- Update CLAUDE.md with GameFramework module table and improved architecture docs
- Remove unnecessary InternalsVisibleTo and L1 wrapper classes

+GameFramework.dll is pure C# and provides infrastructure usable directly in L0:
+
+| Module | L0 Usage |
+|--------|----------|
+| Event | `GameFramework.Event.EventManager` - custom args inherit `GameEventArgs` |
+| ObjectPool | `ObjectPoolManager` - entities inherit `ObjectBase` |
+| Fsm | `FsmManager` - states inherit `FsmState<T>` |
+| ReferencePool | `ReferencePool.Acquire<T>() / Release()` |
+| DataNode | Tree data structure, use directly |
+| DataTable | DataRow classes implement `IDataRow` in L0 |
+
+Modules requiring L1 Unity adapters: Resource, Scene, Entity, UI, Sound.
