Step 5 of milestone 481. Replaces the linked-notes constellation, which had been
stale since note links were dropped (alembic 0024). The colour scheme stays.
packaging/icons.py draws the mark once and renders every variant from it: the
rounded tile (web, desktop), the maskable full-bleed web icon, and the Android
adaptive foreground. The detail (shaft, vane splits, glint) is cut out of the ink
with a mask rather than painted on in yellow, because the Android foreground is
now transparent and its alpha is also the themed-icon silhouette. The old
foreground was the opaque maskable tile, which a themed icon would have drawn as
a solid square.

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)
