📝 Walkthrough

Walkthrough

The PR adds QueryKeyWithDataTag, updates query and infinite-query option overloads across framework packages, adds declaration-emit regression fixtures and a Vue consumer integration, and records patch releases.

Changes

Query options declaration emit

Layer / File(s)	Summary
Shared query-options return types and overloads packages/query-core/src/types.ts, packages/*-query/src/queryOptions.ts, packages/vue-query/src/index.ts	Adds QueryKeyWithDataTag and replaces inline DataTag query-key intersections. Vue Query adds named tagged option types and exports them.
Infinite-query overloads packages/*-query/src/infiniteQueryOptions.ts	Updates infinite-query overload return types to use QueryKeyWithDataTag.
Declaration-emit validation and Vue consumer packages/-query/src/__tests__/, packages/svelte-query/tests/, integrations/vue-declaration-emit/, .changeset/*	Adds exported declaration-emit fixtures, Vue emit/consume configurations, and patch release entries.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to b8759

The change remains mergeable with owner awareness because Svelte query-option overloads may lose caller-provided error typing and fall back to the default error type, causing incorrect TypeScript inference for affected users.

Check name	Status	Explanation	Resolution
Description check	⚠️ Warning	The description only links the issue and prior work, and omits the required changes, checklist, and release impact sections.	Add the template sections, summarize the implementation and motivation, complete the checklist, and identify the release impact and changeset.

Linked Issues check	✅ Passed	The changes address issue [#8453] by making exported queryOptions types nameable during declaration emit and adding regression coverage.
Out of Scope Changes check	✅ Passed	The adapter updates, shared query-core type, declaration-emit fixtures, and changeset all support the reported declaration emit fix.

DefaultError default, preserving custom error types in the tagged query key.
