* 🛟 fix: Auto-Recover from Stale Service Worker Assets After Deploys - 404 missing static assets in the SPA fallback instead of serving index.html - inline recovery script unregisters stale SWs and reloads once on chunk failure - route vite:preloadError into the same recovery path for stale lazy chunks * 🛟 fix: Address Review — SW-Side Recovery, Scoped Unregister, Shared Fallback - importScripts'd sw-heal.js pings window clients on activation and reloads ones that can't pong: stale pages carry no recovery code of their own - scope SW unregistration to the deployment base for subpath installs - preventDefault vite:preloadError only when a recovery reload was initiated - extract createSpaFallback and apply the asset 404 guard to experimental.js
