fix(scripts): standardize source paths and quoting

- install-composer.sh: use $DOTFILES instead of $HOME/.dotfiles
- install-macos-defaults.sh: use $DOTFILES, replace which with command -v
- install-xcode-cli-tools.sh: quote command substitution
- create-nvim-keymaps.sh: quote $DEST in nvim redir command
