Migrate from `registerSW({ immediate: true })` to `useRegisterSW` from
`virtual:pwa-register/svelte`, mirror its `needRefresh` / `offlineReady`
stores into stable layout-local writables, and render a new
`UpdateToast` pill (bottom-center) that surfaces:
- "New version available" + a "Reload" button that calls
`updateServiceWorker(true)`
- "Ready to use offline" (auto-dismiss after 4s) on first install
Adds `[pwa] …` console.info telemetry on register / need-refresh /
apply. Stand-in for the unavailable `updateViaCache: 'none'` runtime
option (RegisterSWOptions doesn't expose it in vite-plugin-pwa 0.21.2):
poll `reg.update()` every 15min, which keeps a too-aggressively-cached
SW file from pinning users on the previous build for up to 24h.
`apps/web/src/global.d.ts` declares the virtual module's surface inline
so svelte-check picks it up without a relative path into node_modules;
the same file pre-declares the Fase-14.3 `__APP_VERSION__` triplet.
PU-01 stubs the registrar via `window.__pwaRegisterStub` (the layout
checks for it before calling the real `useRegisterSW`) so the toast
flow can be driven from a Playwright test without a second build.
