msvc toolset discovery

The msvc toolset discovery tag covers Visual Studio updates that improve how developers locate and select Microsoft C++ compiler toolsets. Current coverage focuses on the June 9 Visual Studio 2026 update, which introduced opt-in cross-install MSVC toolset discovery and pinned C++ compiler resolution within the IDE. This feature can help projects identify available toolsets across Visual Studio installations and use a more deliberate compiler configuration. The same update also added a native Copilot Usage window and a Theme Color Editor, providing context on the broader Visual Studio changes surrounding the msvc toolset discovery feature.
