.SYNOPSIS
    Publishes npm workspace packages to the npm registry.

.DESCRIPTION
    Stages packages in configured order using RepoUtilsSecrets slot Npm.
    Uses npm stage publish so a maintainer approves the version with 2FA.
    Requires npm CLI 11.15.0 or newer. Uses a temporary .npmrc in the workspace root.
