Group membership is fixed at login, so removing (or adding) the docker group does not take effect in the running session. The existing-user migration and the Setup > Security toggles now call `omarchy-state set reboot-required`, so omarchy-update-restart prompts for the reboot that actually applies the change (and the bar shows it pending). A plain log out and back in still works. The migration test now exercises the real removal command and omarchy-state rather than a stub, asserting the reboot flag is set on removal and left alone when the user is already out of the group.
