The uninstaller hardcodes ~/.oh-my-zsh and ~/.zshrc, which fails for
users who set $ZDOTDIR or installed to a custom $ZSH path. The
installer already handles these variables (tools/install.sh line 62),
but the uninstaller does not, leaving files behind or removing the
wrong directory.
Use ${ZDOTDIR:-$HOME} and ${ZSH:-$HOME/.oh-my-zsh} to match the
installer's conventions. Also pass ZDOTDIR through the env wrapper
in uninstall_oh_my_zsh() so it is available to the sh subprocess.
