Backend: PushSubscription model/migration, VAPID config + `cli.py generate-vapid-keys`, push_service.send_push_to_user (upsert-by-endpoint subscribe/unsubscribe, auto-cleanup of expired 404/410 subscriptions), /api/push/* router, and ConnectionManager now tracks connected user IDs per room so chat.py can push only to offline members after broadcasting to online ones. Two test-infra bugs found and fixed along the way: send_push_to_user takes the caller's AsyncSession and is awaited inline rather than fired via asyncio.create_task with its own session (background tasks were outliving the test event loop); and the ws_client fixture now uses NullPool to eliminate a connection-pool checkout race that was failing WS tests intermittently. Frontend: service worker rebuilt with vite-plugin-pwa's injectManifest strategy (custom src/sw.ts) so it can add push/notificationclick handlers alongside the existing precaching and StaleWhileRevalidate routes ported over from generateSW. New subscribe/unsubscribe flow (lib/push.ts, api/push.ts) with a toggle in the account menu. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
