Registry-agnostic package maintenance/abandonment scorer (pure) API

Pure, registry-agnostic maintenance scorer: given last-publish age (days, or an ISO lastPublished date), optional release count, and an optional deprecation flag, returns a verdict (maintained/aging/at-risk/abandoned/deprecated/unknown), a 0-100 health score, and the contributing reasons + band definitions. Free to run, no upstream. Distinct from dev-abandoned (npm-only, joins GitHub commits) — this works for ANY ecosystem from publish metadata alone. Answers 'given this package's last-release date, is it likely abandoned?'.
