fix: PWA manifest was never linked, icons 404'd; add install prompt (v0.64.0)

layout.tsx pointed <link rel="manifest"> at /manifest.json, but the actual generated route (app/manifest.ts) serves at /manifest.webmanifest -- the manifest was silently never picked up. Its icons also referenced icon-192.png/icon-512.png, which don't exist (only the .svg versions do). Both together meant Chrome/Android install eligibility was broken with no visible error. Also adds apple-mobile-web-app meta tags + viewport-fit=cover for iOS home-screen installs, and a dismissible install banner driven by the standard beforeinstallprompt event (Chromium-only by spec).
