add ntfs.sys standalone driver target, change default usb vhd layout formatting to ntfs, implement Fat32CreateDir for directory creation support in the fat32 file system driver, add a dedicated HAL serial output endpoint for COM1 writes in hal_serial.c and subscribe serial to HAL text streams, introduce waitable kernel timers with KeTimerCreate, KeTimerSet, and KeTimerCancel alongside spinlock-protected global timer list initialization and scheduler tick tracking, implement SyscallWriteFileAsync system call for asynchronous non-blocking file writes, refactor NetSocketConnect and NetSocketSendTo to use generic SYS_SOCKET_ADDRESS_K structures instead of being hardcoded to IPv4, update gethostbyname and DNS name resolution to support IPv6 parsing via ResolveNameFamily, update tcpserve.exe with -4 and -6 command-line flags to accept and display IPv6 addresses, append size and version headers to all kernel telemetry and statistics structures including SYS_PMM_STATS, SYS_CPU_STATS, and SYS_SCHEDULER_STATS, update winmm timeGetTime to look up high-resolution hardware frequencies via SysGetTickFrequency, integrate 14 native smoke test applications.
