Instead of sending stty commands through the user's terminal session
(which causes 'inappropriate ioctl' errors), send SIGWINCH signal to
the docker exec process on the host. Docker exec should forward this
to the container process, causing the shell to re-read its terminal size.
This avoids:
- Visible stty commands in the terminal
- ioctl errors from stty
- Interference with user's shell session
