Subject: [PATCH] fix(installer): allow root execution in archiso by shimming
 sudo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When running as root (archiso chroot context), all three TUI installers
previously died immediately. Replace the hard die with a sudo passthrough
shim ($TMP_D/bin/sudo → exec "$@") prepended to PATH, so every module's
`sudo pacman`, `sudo systemctl` etc. just executes directly as root.
The shim lives in TMP_D and is cleaned up by the existing EXIT trap.
