[BUG] `/terminal-setup` with WezTerm assumes that the only possible config is `~/.wezterm.lua` and creates it if the file isn't found.

What's Wrong?

Wezterm looks for configuration files in various locations (see docs). However, /terminal-setup assumes that the configuration file is only in ~/.wezterm.lua. If this file is not found, it creates one with only a keybinding setting for Shift-Enter.

If a user has configs in ~/.config/wezterm/wezterm.lua, they won't be used by Wezterm anymore, since ~/.wezterm.lua takes priority. This caused problems for me and might cause problems for others as well. Please fix this.

What Should Happen?

Claude should understand which config file is in use and modify it.
