  Whether the termios NIF build is skipped for this host.

  The NIF is POSIX-only and needs a C toolchain. Skipping it lets the
  pure-Elixir majority of the library compile and its tests run on a host
  without one — notably Windows, where `/dev/tty` and termios don't exist and
  only the `:test` backend is meaningful. `Harlock.Terminal.Termios` already
  degrades to a logged warning when the NIF is absent, so the skip surfaces as
  "terminal control unavailable" rather than a compile failure.

  Set `HARLOCK_SKIP_NIF=1` to force the skip on a POSIX host too.
