Migrate the former install-only public/sw.js to a custom (injectManifest)
service worker built from ui/src/sw.ts by vite-plugin-pwa. It precaches the
app shell + hashed assets (Workbox) so an installed web PWA cold-launches with
no network, and falls in-scope navigations back to the precached shell (the
hash router resolves the route client-side). This is the C1 prerequisite for a
usable offline mode: without it a cold offline launch cannot load the bundle.
- ui/src/sw.ts: skipWaiting + clientsClaim + cleanupOutdatedCaches +
precacheAndRoute(__WB_MANIFEST) + a NavigationRoute fallback to index.html,
deny-listing the RPC path and /_gm. The Connect stream and API POSTs are
never precached nor intercepted.
- vite.config.ts: VitePWA(injectManifest); manifest:false (we ship our own),
injectRegister:false (registration stays manual + web-only in pwa.svelte.ts),
disabled in the mock build (Playwright unperturbed); landing + polyfills
excluded from the precache.
- Removed public/sw.js; the registration path (dist/sw.js at /app/) is unchanged.
- New dev deps: vite-plugin-pwa + workbox-{core,precaching,routing}.
Docs: ARCHITECTURE + gateway/README. Offline cold-launch is contour-verified
(the mock e2e harness disables the SW).
