Subject: feat(archsetup): add config file support for unattended installs

- Add --config-file PATH CLI flag
- Add load_config() function to source config variables
- Support USERNAME, PASSWORD, AUTOLOGIN, NO_GPU_DRIVERS config options
- Create archsetup.conf.example with documented options

Follows same pattern as archzfs project for consistency.
