📝 Walkthrough

Walkthrough

This PR introduces test infrastructure for the isRestoring context behavior in svelte-query. It adds a test component and corresponding test suite that verify queries remain idle during restoration periods, ensuring queryFn is not called while isRestoring is active.

Changes

Cohort / File(s)	Summary
isRestoring Test Component `packages/svelte-query/tests/createQuery/IsRestoringExample.svelte`	New test component that initializes a QueryClient with `isRestoring` context set to true, creates a query with a provided `queryFn`, and renders query state (`status`, `fetchStatus`, `data`) for test assertions.
isRestoring Test Suite `packages/svelte-query/tests/createQuery/createQuery.svelte.test.ts`	New test file using fake timers to verify that `queryFn` is not invoked and query state remains `pending`/`idle` when `isRestoring` is active, both immediately and after timer advancement.

Poem

🐰 A rabbit's tale of queries at rest,
When restoring, they take a test,
No fetch calls ring while timers fly,
State stays idle, data shy! 🧪✨
