What's Wrong?

When the TERM environment variable is set to xterm-kitty, while also running in kitty, the Write tool produces CRLF line endings on linux which break a lot of things.

Setting the TERM to xterm-256color fixes the output for the Write tool while running in kitty.

What Should Happen?

Write tool produces standard line endings not CRLF.
