Windows GamepadManager via vigem-client (ViGEmBus) — the uinput-xpad analogue: one virtual Xbox 360 controller per client pad index, created lazily on first State. GameStream/Moonlight already uses the XInput conventions (low-16 button bits, sticks -32768..32767 +Y up, triggers 0..255), so the GamepadFrame->XGamepad mapping is 1:1. Replaces the non-Linux GamepadManager stub (same new/handle/pump_rumble API the m3 PadBackend drives, so no m3 change). Graceful when ViGEmBus is absent (gamepad disabled, session continues). Compiles clean on Windows + Linux; live-test needs the ViGEmBus driver + a physical pad. Rumble back-channel is a TODO (ViGEm notification API).
