replace the VHD/diskpart disk image pipeline with a directory-based vvfat root, we'll see when it breaks, fix /O2, add an all_tests, generalize the fat32 driver into a fat 16+32 driver, change policy on volume drivers, collapse KCPU's fields into a single atomic KE_CPU_STATE state machine, move scheduler ticking to per-CPU LAPIC timers, gate verbose SMP topology logging behind selftest diagnostics and add SMP pool-checkpoint validation around AP admission, add checked intrusive list helpers behind a new KE_DEBUG_LIST_CHECKS flag, add ObInitializeObjectHeader/ObTryReferenceObject, add waitable display clock objects and a SYS_OPEN_DISPLAY_CLOCK syscall for vsync-style waits, refactor kernel input into a per-queue KE_INPUT_CONTEXT with its own key/mouse ring buffers and DPC-driven key repeat, add KeInputQueuePeekEvent/ReadEvent/WaitKey and a SYS_QUERY_GLOBAL_INPUT_STATE syscall, split the kernel pool allocator out of mm_virt, new video files!
