install-lint provisioned chrome-headless-shell on every run, and `make lint` runs install-lint once per lint target in parallel whenever its stamp is not fresh. On CI the stamp never is (eslint lives in node_modules, not on PATH), so one lint job provisioned 16 times (run 38455552981). As root, puppeteer's --install-deps runs `apt-get satisfy` even for an installed browser, and two of those at once fail on the dpkg lock; a failed provisioning then deleted the shared browser cache while lint-mermaid could be rendering with it. The browser is now provisioned only when it is not installed, and --force drops its cache so `make install-lint-force` still reinstalls it with its libraries.
