Python 3.14 enforces stricter type and size checking for fcntl.ioctl()
buffer arguments. The previous code passed a short 4-byte string ('1234')
to TIOCGWINSZ, which worked by accident in older Python versions but causes
a SystemError ("buffer overflow") in 3.14.
TIOCGWINSZ expects an 8-byte (4x 16-bit) buffer corresponding to
(rows, cols, xpix, ypix). Use an 8-byte bytes literal instead and unpack
the first two values.
Tested with Python 3.11, 3.13, and 3.14.
