- Move frontend/utils/ to frontend/lib/ to avoid Nuxt unimport scanner incorrectly extracting function parameter names (value, fallback) as module-level exports, which injected phantom imports that broke all client-side JavaScript execution - Update all import paths across 13 files from ~/utils/ to ~/lib/ - Add timeout (5s) and negative cache (60s TTL) to WCDB realtime ensure_connected() to prevent open_account() from hanging indefinitely when the WeChat database is locked - Reorder selectContact() to fire loadMessages() before navigateTo() so the message fetch starts before route navigation triggers Suspense - Add watch: false to SSR useAsyncData calls to prevent unnecessary re-fetching on client-side route changes
