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.
Replace raw HID report forwarding with typed absolute mouse, relative
mouse, and keyboard messages.
Expose absolute and relative modes as separate Mouse collections because
Windows MouHID requires one X/Y motion mode per mouse device.
Move the reusable named-pipe endpoint and shared support code into
the LGCommon static library.
Run a dedicated server in LGIdd and a reconnecting client in
LGInput, with device-lifecycle handling and report framing.
Refactor the helper pipe to use the same endpoint implementation.
