docs({react,preact,vue,solid,svelte,angular}-query): describe when 'status' is 'error', 'success' or 'pending', and that 'data' is 'undefined' when 'select' throws with 'initialData' - #12601
The @returns of useQuery (createQuery in Svelte, injectQuery in Angular) described status in a way that does not match QueryObserver:
A failed attempt does not set status to error while it is being retried. status stays pending (or success with data) until the retries run out.
status is error when select throws, even if the fetch succeeded.
With placeholderData, status is success although there is no cached data.
A refetch that starts without cached data clears the error, so status goes back to pending, or to success with placeholderData.
The initialData overload also said that data is never undefined, but data is undefined at runtime if select throws on its first call.
This updates the docs:
Without initialData: status is error if the query has an error from a fetch that failed after its retries or if select threw, success if the query has data to display (including placeholderData), and pending otherwise.
With initialData: status is typed as success or error, and is error under the same condition and success otherwise. The overload description says that data is typed as never undefined, and is still undefined at runtime if select throws on its first call.
The same wording is applied to react-query, preact-query, vue-query, solid-query, svelte-query, and angular-query-experimental (status() and quoted values in Angular, where the initialData note is in the @returns). The rest of each @returns, such as Vue's refs and state or Solid's store, is unchanged.
The reference pages are regenerated with pnpm run generate-docs.

Walkthrough
Query result documentation now describes fetch failures after retries, select exceptions, and placeholderData across framework package declarations and reference pages. It clarifies that a first-call select exception can leave runtime data undefined despite defined initial data. Source links were updated where declaration locations changed. No public signatures or runtime implementations changed.
Overload documentation describes error status after fetch failures following retries or select exceptions. It describes success when data is available, including placeholderData, and pending otherwise. It also notes that a first-call select exception can leave runtime data undefined with defined initial data.
This PR only changes documentation. Some status descriptions may still overstate when a query returns to pending, and one result-property table disagrees with the new wording. Neither affects runtime behavior, so the risk is low. Fix the wording before or soon after merge.

The title names the docs change across the six query libraries and the two status rules, and it names the initialData behavior with select throwing. It is accurate and specific, but it is long at 182 characters, so it is not concise.
Full details: Description check
Explanation
The description explains the motivation and the concrete changes: it lists the four status mismatches with QueryObserver, describes the updated @returns wording for the no-initialData and initialData overloads, names the affected packages (react, preact, vue, solid, svelte, angular), and says the reference pages were regenerated. It fills in the template's Changes section and the checklist, and marks the release impact as docs-only. The template's sections are all present, and the author-provided information is specific enough to review.

Align the result-property table with the revised status description.
A data-less refetch can return to pending after a completed failed attempt. Defined placeholderData can also produce success before a response. This table excludes both cases, so it conflicts with the revised Returns section. Update the JSDoc that generates the table and regenerate the affected reference pages.

- Line 75: Update the useQuery overload JSDoc in each affected framework to
distinguish initial query data from selected result data: clarify that although
initialData is defined, data may be undefined if select throws on its first
call. Align the guarantee in the surrounding overload description with this
runtime exception.
Review comments at @packages/angular-query-experimental/src/inject-query.ts:
- Around line 95-96: Update the matching status descriptions across all six
packages to distinguish missing query-cache data from missing observer data: a
refetch restores pending only when query-cache data is absent, and do not claim
that it clears a select error. Keep the descriptions consistent with fetchState
retaining the error when cached data exists.

Qualify when a refetch restores pending.
If cached query data exists and select throws on its first call, the observer returns undefined data with status error. A refetch then starts without displayable data. However, fetchState receives the defined cached data and does not reset the status. The observer also retains the select error.
Distinguish missing query-cache data from missing observer data. Do not promise that a refetch clears a select error. Apply this correction to the matching descriptions in all six packages.
