CVE-2026-84994

### Summary A Qwik server in the default configuration can be crashed with one unauthenticated HTTP request. During qwik-json body parsing, `ResourceSerializer.$fill$` does `Promise.resolve(resource._resolved)`. If `_resolved` is a plain object whose `.then` is a QRL for an unregistered symbol, the async QRL rejects, the rejection is orphaned, and Node terminates the process via its default unhandled-rejection policy. ### Impact One unauthenticated request crashes the server. Looping keeps every replica dead as long as the attacker sends requests.
