refactor: replace zsh deps with runtimeShell, migrate scripts from symlinkJoin to runCommand, add missing assertions and deps

Scripts: Migrated from symlinkJoin to runCommand; replaced zsh
dependency with pkgs.runtimeShell across polybar, scripts, and
fzf-launcher
Assertions: Added gopass/gpg checks for neomutt, signing checks for git,
git dependency for lazygit, file-preview deps for lf, desktop/kitten
checks for scripts
Lazygit: Fixed mkIf placement, imported assertions
Neomutt: Removed verbose keybinding descriptions
Nixvim: Removed <c-c> notification-clear mapping
File preview: Replaced libreoffice document preview with pandoc/antiword
(terminal-based)
Fzf launcher: Fixed bash compatibility (setopt → shopt -s)
Deps: Added coreutils, fontconfig, antiword, pandoc, util-linux, bash,
findutils, grep, sed, gawk, ncurses to various scripts
