fix(zsh): workaround for initial termwidth on zlogin

When opening wezterm & termux for the first time, termwidth (tput cols)
always resulting 80 columns. That would overflow the bubble chat when
zsh login on my mobile screen with termux. Hence `$COLUMNS` env variable
is correctly detecting the actual screen / terminal width on zsh login.
