Windows InputInjector via SendInput (Win32 KeyboardAndMouse), mirroring the wlroots backend: absolute mouse (MOUSEEVENTF_VIRTUALDESK normalized to the virtual desktop), relative mouse, scancode keyboard (MapVirtualKeyExW + extended-key flagging), scroll (no sign flip — Windows wheel matches GameStream), buttons. Client already sends Windows VK codes (no keycode table). Reattaches the thread to the input desktop (OpenInputDesktop/SetThreadDesktop) to survive UAC/lock switches. New Backend::SendInput, the Windows auto-default in default_backend(), open() arm, windows-crate features. Compiles clean on Windows + Linux. Live injection validates with the in-session host run (SendInput is desktop-isolated from an SSH network logon).
