CI already disables npm lifecycle scripts, but ordinary installs from
the repository still run them. Set `ignore-scripts = true` in `.npmrc`
so developer and maintenance installs use the same default. Keep the
existing seven-day `min-release-age` policy for new resolutions. Require
`npm>=11.10.0` through `engines.npm` and `engine-strict`, while
retaining `devEngines` for newer clients; older installers can otherwise
ignore `devEngines` and the age setting. Pin the build and checksum
workflows to Node.js `24.19.0` so their bundled `npm` supports the
policy. Explicit project commands such as `npm run package` remain
available.
Related: astral-sh/ruff-action#401 applies the matching `npm` defaults,
and astral-sh/ruff-action#411 adds the same legacy-aware version floor.
astral-sh/ruff#27837 applies the install-script default to Ruff's
JavaScript projects. astral-sh/setup-uv#1027 separately adds
registry-signature and provenance verification.
