actop 1.6.4

Fixed

• Process CPU% was understated ~41.7x on every Apple Silicon machine. The
  two CPU-time fields in proc_pidinfo (pti_total_user / pti_total_system)
  are mach absolute-clock ticks, not nanoseconds — on Apple Silicon the
  timebase is 125/3 (1 tick = 41.667 ns). get_native_processes() returned
  those raw ticks as cpu_time_ns, so every process's CPU% read ~2.4% of its
  real value (e.g. 1.2 s of burned CPU appeared as 0.03 s). proc_pidinfo'
  actually reports nanoseconds only by coincidence on Intel (timebase 1/1),
  which is why the offset-verified offsets never surfaced the unit. The module
  now reads mach_timebase_info once at import and converts via integer math
  (_mach_ticks_to_ns). Per-process cpu_time_share and watt attribution are
  ratio-based, so they were never affected. See Apple openradar FB9546856.
