D4: pass --ignore-scripts to per-platform npm publish/pack

The main npm package already publishes and packs with --ignore-scripts,
but the per-platform subpackage loop did not: `npm publish --access
public`, its retry, and the per-platform `npm pack` all ran lifecycle
scripts from the package directory with the npm token in scope.

Add --ignore-scripts to all three, matching the main package, so no
prepublish/prepare hook can execute during a release.
