Introduce a Roslyn analyzer to enforce unique ownership semantics for structs marked with the `[NonCopyable]` attribute. Added a corresponding code fix to resolve violations by suggesting the use of `Share()` or other ownership transfer methods. Key changes: - Added `StructCopyCodeAnalyzer` to detect invalid struct copies. - Implemented `StructCopyCodeFixProvider` to provide code fixes. - Created `Misaki.HighPerformance.Analyzer` and `CodeFixes` projects. - Added unit tests for the analyzer and code fixes. - Introduced `UniquePtr<T>` and `SharedPtr<T>` for pointer ownership. - Added a Visual Studio extension project and packaging support. - Updated `UnsafeUtility` to use `nint`/`nuint` for indices.
