Make ThoughtSync installable ("Add to Home Screen") without going
offline-first (the Android app is the real offline client, M5):
- web app manifest (name, icons incl. maskable + SVG, standalone, theme)
- generated PNG icon set + apple-touch-icon + favicon, from committed
SVG sources (a linked-thoughts constellation on the brand tile)
- minimal service worker: installable shell only — caches just an
offline fallback page, never the app shell / hashed assets / API, so
data stays fresh and deploys never serve a stale shell
- register the SW in main.ts (progressive enhancement; failures ignored)
- index.html: manifest/icon links, apple-mobile meta, description
- backend: register the .webmanifest MIME type so it serves as
application/manifest+json
- README: note that install needs a secure context (HTTPS/localhost)
