refactor syscall ABI and FAT32 driver to use request structs and string views natively, enforce handle access rights on object lookup, add scheduler statistics tracking, fix KiSchedule to prevent 50% idle throttling on CPU-bound threads, better document x64 initial user stack alignment, fix process teardown to properly signal exit events and manage thread counts, optimize doom file I/O with a custom handle struct to internally track position and size, add SubsystemData to TEB for generic thread-local state, apply PAGE_NX to non-executable PE sections in the loader, update native apps, tests, and shells to match new APIs, update kernel32 directory retrieval.
