"""Regression tests: installers provision cua-driver (Computer Use).

Policy: choosing Computer Use should be a config flip, not a surprise
multi-minute binary fetch. The installers pre-install cua-driver
(best-effort, skippable), and the dashboard toggle auto-installs when the
binary is still missing (see test_web_routers_tools_install_on_enable.py).
