// CHANGE: resolve clone/open shortcut requests from argv + npm lifecycle metadata
// WHY: support pnpm run clone/open <url> without requiring "--"
// QUOTE(ТЗ): "Добавить команду open. ... Просто открывает существующий по ссылке"
// REF: user-request-2026-01-27
// SOURCE: n/a
// FORMAT THEOREM: forall a,e: resolve(a,e) -> deterministic
// PURITY: CORE
// EFFECT: Effect<CloneRequest, never, never>
// INVARIANT: command requested only when argv[0] or npmLifecycleEvent is clone/open
// COMPLEXITY: O(n)
