Build LGInput as an independent UMDF driver with its own entry point, service, tracing, and binary. Expose absolute pointer, relative mouse, and keyboard collections with a guarded report queue. Keep LGIdd as the startup and deployment project. Give it a non-linking build/package dependency on LGInput so F5 stages both driver stacks and installs them together through LGIddInstall, while the two UMDF binaries remain independent for future IPC. Stage both DLLs for the NSIS installer, retain the WDK UMDF remote-debug startup attachment, and move CSRWLock into LGCommon for the input driver's report queue.
