* Closes#36942
* Fixes#19265
Replaces the SSE-based push channel (`/user/events`) with a WebSocket
endpoint (`/-/ws`).
### What changes
- **New `/-/ws` endpoint** (authenticated). One WebSocket per origin,
shared across tabs via a single `SharedWorker`.
- **Pubsub broker** (`services/pubsub`) for fan-out by topic, behind a
`Broker` interface. `MemoryBroker` is the default (single process); a
Redis backend is available for multi-process setups, configured via
`[websocket].PUBSUB_TYPE` / `PUBSUB_CONN_STR`. The internal Gitea queue
was not usable here because it has FIFO/single-consumer semantics.
- **Push-only event production.** Events are emitted by write-triggered
notifiers — `NotificationCountChange`, `PublishStopwatchesForUser`, and
the logout publisher — wired into the existing `notify.Notifier`
interface. No server-side pollers.
- **Typed pub/sub on the client.** `web_src/js/modules/worker.ts` is a
singleton transport; features subscribe per event type via
`onUserEvent('notification-count', cb)` instead of branching on
`event.data.type`.
- **Wire contract** (`UserEventType` union) is shared between the worker
and consumers via `web_src/js/types.ts`, kept in sync with
`services/websocket/events.go`.
- **Client-side periodic polling fallback** kicks in only when the
WebSocket cannot be established (e.g. proxy blocks WS, browser lacks
module-SharedWorker support).
### What's removed
- `modules/eventsource` (SSE manager, run loop, messenger).
- `/user/events` route and `tests/integration/eventsource_test.go`.
- All server-side polling for stopwatches and notification counts.
### Stopwatch multi-tab fix
The navbar stopwatch icon was previously rendered conditionally on `{{if
$activeStopwatch}}`, so tabs loaded before the timer started had no DOM
element to update. The icon and popup are now always rendered (toggled
with `tw-hidden`), and the start/stop/cancel handlers POST silently so
all open tabs reflect the change in real time.
### Deployment note
WebSocket needs the upgrade headers to pass through a reverse proxy,
e.g. for nginx:
```nginx
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
```
Without them the WebSocket cannot be established, and after 3
consecutive failed opens the shared worker signals `push-unavailable`:
the notification count and stopwatch fall back to periodic polling on
the existing `[ui.notification]` timeouts. Real-time push is lost, the
features keep working. The reverse-proxy docs need the same note (see
the `docs-update-needed` label).

After using CSP nonce, the "onerror" doesn't work anymore. Change it to
use a global variable to detect
Also help users like #37379 to catch errors more easily.

1. Filter out errors that contain `chrome-extension://` etc protocols
2. Extract filtering into its own function and test it
3. Fix the `window.config.assetUrlPrefix` mock, guaranteed to end with
`/assets`
4. Remove useless `??` and `?.` for properties that always exist

Replace webpack with Vite 8 as the frontend bundler. Frontend build is
around 3-4 times faster than before. Will work on all platforms
including riscv64 (via wasm).
`iife.js` is a classic render-blocking script in `<head>` (handles web
components/early DOM setup). `index.js` is loaded as a `type="module"`
script in the footer. All other JS chunks are also module scripts
(supported in all browsers since 2018).
Entry filenames are content-hashed (e.g. `index.C6Z2MRVQ.js`) and
resolved at runtime via the Vite manifest, eliminating the `?v=` cache
busting (which was unreliable in some scenarios like vscode dev build).

None of the frontend js/ts files was touched besides these two commands
(edit: no longer true, I touched one file in
61105d0618
because of a deprecation that was not showing before the rename).
`tsc` currently reports 778 errors, so I have disabled it in CI as
planned.
Everything appears to work fine.
