fix(archsetup): copy archsetup to user directory before stow

Previously, stow created dotfile symlinks pointing to wherever archsetup
was run from (e.g., /root/archsetup or /tmp). If run from a location
inaccessible to the user, zsh would fail to read its config on first
login and prompt for new user setup.

The fix copies archsetup to ~/code/archsetup before running stow, ensuring
symlinks always point to a user-accessible location.

Also adds a test to verify dotfiles are readable by the user (not just root).
