The uinput devices the input adapter creates were never forwarded into the guest: the input-linux bridge was external (manual monitor object_add), so it was lost on every reconfigure and whenever the kernel-assigned device numbers changed. Make the vmhost seam -- which already owns the VM's single QMP connection -- add the input-linux objects itself on reaching READY (A=keyboard +abs with grab_all, B=mouse) and object_del them on teardown. The input adapter publishes the uinput evdev paths into a per-endpoint home; discovery attaches input before vmhost so the paths are ready. No second QMP socket or connection. Also move the mouse buttons (incl. middle) and the wheel onto device B, so B is a complete relative mouse and A is keyboard+abs only. Bump 0.3.8.
