SboxSuperuser/Engine/Vendor/ImGui/ImGuiHost.cs
A small host helper for ImGui input integration. It exposes a clipboard provider delegate, a flag to simulate input, tracks keyboard keys that fail, and provides PollKeyDown to query S&box keyboard state for ImGui keys while handling unavailable keys and runtime exceptions.
