refactor(config): Clean up and reorganize Emacs configuration

Remove unused packages (EMMS, jinx, god-mode), simplify terminal
setup with ido instead of vertico/orderless, and reorganize
keybindings. Add new packages (debase, discomfort, git-timemachine,
edit-indirect) and improve EXWM, dired, and theme
configurations. Move restart-fcitx5 to kbd-func and update Linux
PATH for Guix.
