docs(examples/{react,solid,vue}): add offline examples for TanStack Router, React Router and Solid Router, and replace the discontinued '@tanstack/react-location' - #12483
Uses file-based TanStack Router for the offline example in React, Solid and Vue. examples/react/offline used @tanstack/react-location, the predecessor of TanStack Router, which has not been released since 3.7.4, and examples/solid/offline had no router.
React: rename examples/react/offline to offline-tanstack-router and its package to @tanstack/query-example-react-offline-tanstack-router.
Replace @tanstack/react-location with @tanstack/react-router and add @tanstack/router-plugin, which generates src/routeTree.gen.ts.
Split the app into routes/__root.tsx, routes/index.tsx and routes/$movieId.tsx.
The router gets queryClient and isRestoring through createRootRouteWithContext, and isRestoring comes from useIsRestoring via <RouterProvider context={{ isRestoring }} />.
The $movieId loader keeps the previous logic: use cached data, and only fetch while online and not restoring. It returns undefined instead of {}.
Preloading uses defaultPreload: 'intent' and defaultPreloadStaleTime: 0 instead of preload={1}, and Detail gets the client with useQueryClient().
Solid: rename examples/solid/offline to offline-tanstack-router and replace the signal-based page switch with the same routes, so the detail page has a URL and survives a reload.
isRestoring is passed as an accessor, because the Solid RouterProvider applies its context only once.
Vue: add examples/vue/offline-tanstack-router, based on offline-vue-router, with *.ts route files and *.component.vue components. The $movieId loader keeps the beforeEnter logic of offline-vue-router and reads queryClient.isRestoring.
Solid: add offline-solid-router (@solidjs/router with preload).
In the React Router and Solid Router examples, loaders run outside the component tree, so isRestoring is a module variable that PersistQueryClientProvider clears in onSuccess / onError.
docs/config.json: label the TanStack Router examples as Offline Queries and Mutations (TanStack Router) and list them first, followed by the React Router and Solid Router examples.
docs/framework/react/guides/mutations.md: update the offline example link.
docs/framework/{vue,preact,angular}/guides/mutations.md: these pages inherit the OfflineExampleLink section from the React guide, which resolved to a non-existent examples/offline. Point Vue to offline-vue-router and Preact to offline-preact-iso, and drop the section for Angular, which has no offline example.
pnpm-lock.yaml: rename the React and Solid importers, add the new importers and swap the dependencies.

Walkthrough
The pull request separates React and Solid offline examples by router, adds a Vue TanStack Router offline example, and updates example listings and mutation-guide links. The examples demonstrate persisted queries, paused-mutation resumption, movie lists and details, and comment updates.
The example adds movie API and query definitions, persisted query state, and mutation defaults. It starts the mock worker before rendering. The previous generic React app implementation is removed.
The generated route tree registers the root, list, and detail routes. The list and detail views display query states. The detail view optimistically updates comments, restores prior data on error, and invalidates the query when settled.

This change reorganizes and adds offline-query examples and their documentation links. No remaining defect was found at the current head, and the earlier concerns about the Next.js Pages Router example no longer apply because that example is not present.

Full details: Title check
Explanation
The title names the docs and example scope (offline examples for TanStack Router, React Router, Solid Router and Next.js across React, Solid and Vue) and the replacement of the discontinued '@tanstack/react-location'. The changeset includes all of these: new router-specific example folders, the React and Solid renames to offline-tanstack-router, docs/config.json and mutation-guide updates, and the react-location swap. The title is long (171 characters) and lists many items, but it still describes the main change accurately.
Full details: Description check
Explanation
The description follows the template's required sections: '🎯 Changes', '✅ Checklist', and '🚀 Release Impact'. The Changes section gives a detailed, file-level account of the motivation, the React, Solid and Vue changes, the new examples, the docs updates, and the lockfile. All three checklist items are ticked. The Release Impact section marks the change as docs/CI/dev-only. The description does not state test results for pnpm run test:pr, but the template only asks that the item be checked, so this gap is minor.
Full details: Docstring Coverage
Explanation
Docstring coverage is 29.41% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 34 functions across 60 files. (12 skipped: 12 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

Use unthrottled saves for the pages-router persister.
The default persister waits up to one second before it writes a save that follows another save. A mutation queued offline in that window can be missing from localStorage after a quick reload. The pending timer does not run during unload, so the mutation cannot resume. This example tells users to reload, so the example can drop a queued edit.

If a user submits two comments for one movie while offline, both mutations can resume concurrently. The older request can complete after the newer request and leave the older comment on the server. Add a movie-specific scope so paused mutations execute in submission order, including after restoration.

Return 404 when a POST names no movie.
If a POST uses an unknown id, this loop changes nothing and the handler still returns success. The client then treats the update as complete instead of reporting a failed mutation. Find the movie before the POST branch and return 404 when it does not exist, as the GET branch already does. (raw.githubusercontent.com)
