Found while working on calendar.worldapi.org #3 — it blocks that ticket.

Repro: Try to serve /sw.js from a .hl file: routes only serve static files or components; no worker realm/compile target exists.

Observed: A service worker must be a hand-written .js file.

Expected: A Hybriel-compiled service worker (fetch/install events, caches) that hl:web can serve and register.

Taken with #95: hl:web generates and registers the service worker itself from the manifest (COMPONENTS.md §10), so no app writes one. Whether apps should also be able to write their own worker code in Hybriel is a separate question; this ticket is answered by the generated one.

Fixed on master (62e18099, 8f3593bf). appIcons in project.hl serves the manifest and links it in the head (plus apple-touch-icon and theme-color). offline = [Page, …] gives the app a generated service worker (no app JavaScript): it precaches the shell and the listed pages, keeps state in IndexedDB, and queues emits made offline, which replay on reconnect. notify, notifyAt and notifyIn fire only while the app is open; waking a closed app needs a server push. demo-notes shows all of it, and its gate checks Chrome installability errors = none. See COMPONENTS.md §10.
