Sanitize payload, hydration, and calls from push-http before you store them.
Any connected page can send push-http. The handler bounds url and title. It stores payload and hydration as received, without size limits. It also stores calls without checking the shape of each element. A malformed report can therefore put arbitrarily large or wrongly shaped data into shared state. The inspector then crashes, for example at h.skipHydrationHosts.length or at h.warnings.length when hydration is {}. Validate the shapes and apply size caps, the same way sanitizeRules does.

Record canceled HTTP requests.
When a request is canceled before it emits a response or error, the interceptor teardown only unsubscribes the source. It does not call done, so the HTTP timeline omits the request. This is reachable when httpResource cancels an in-flight request after its input changes. The omission violates the documented “every HttpClient request” timeline and hides canceled requests from the inspector.
Record status: 0 with error: 'cancelled' during teardown, but only when no response or error was recorded.

Merge both duplicate dependency objects.
packages/ng-devtools/package.json declares peerDependencies and peerDependenciesMeta twice. A last-key-wins JSON parser retains only the later objects, so the Angular and RxJS peer declarations and metadata are discarded. Merge both objects and retain @angular/common, @angular/core, rxjs, and vite as optional peers.
