ci(renovate): enforce 3-day minimum release age for npm packages (#462)
* ci(renovate): enforce 3-day minimum release age for npm packages
Extend the Renovate config with the official 'security:minimumReleaseAgeNpm'
preset so that Renovate waits 3 days after publication before creating PRs
for any npm/pnpm dependency. This adds a buffer against unpublished or
freshly-broken releases (e.g. malicious packages, npm unpublish window,
transient registry/lockfile resolution issues).
