feat(archsetup): make the claude-code install optional

The claude-code step is a curl|sh from a third party, and not every user wants AI tooling. I put it behind INSTALL_CLAUDE_CODE (default yes, so current behavior is unchanged), with matching --claude-code / --no-claude-code flags. I wired it the same way as AUTOLOGIN and NO_GPU_DRIVERS: config mapping, a validate_config yes/no check, and a guard around the install block. I also documented the key in archsetup.conf.example.
