install.sh rejects --no-skills with "unknown option" (rc=1) and neither
installer has --skip-computer-use / -SkipComputerUse: the installer no
longer pre-installs cua-driver at all. Point the skills page at the setup
prompt / hermes skills opt-out, and describe cua-driver as the PM-pinned
package that hermes computer-use install prepares (it never runs the
upstream installer now).
