Move named pipe writes off the LGMP input worker so a stalled LGInput endpoint cannot block queue draining or lease maintenance. Coalesce motion only under queue pressure while preserving mode, button, wheel, and keyboard transitions. Reset HID state after discontinuities and carry all 32 mouse button bits through the pipe and HID reports.
