fix(query-codemods): skip key transformation without react-query import

[raashish1601]

Summary

Avoids running the v4 key transformation codemod when a file does not import
eact-query.

• Adds an early import check in packages/query-codemods/src/v4/key-transformation.cjs.
• Returns original source when no
  eact-query import is found.
• Adds a fixture/test to assert no-op behavior for non-React Query files.

Verification

px -y pnpm@11.1.0 -C tanstack-query --filter @tanstack/query-codemods test:lib

• pnpm test:eslint (direct pnpm) is blocked in this environment by toolchain mismatch; this is unrelated to the code change.

Summary by CodeRabbit

• Bug Fixes

  • Fixed codemod to properly handle files without React Query imports by skipping transformation.

• Tests

  • Added test fixtures and test cases for scenarios without React Query imports.

📝 Walkthrough

Walkthrough

The PR adds a guard to the key-transformation codemod that detects missing React Query imports and returns the source unchanged rather than attempting transformation. Test coverage is added with a fixture pair and test case validating that files without React Query imports are not modified.

Changes

Guard for files without React Query imports

Layer / File(s)	Summary
Early return guard in codemod packages/query-codemods/src/v4/key-transformation.cjs	Codemod checks for an ImportDeclaration from react-query and exits early, returning original source if the import is absent; otherwise runs transformers normally.
Test case and fixtures for guard validation packages/query-codemods/src/v4/__tests__/key-transformation.test.cjs, packages/query-codemods/src/v4/__testfixtures__/no-react-query-import.input.tsx, packages/query-codemods/src/v4/__testfixtures__/no-react-query-import.output.tsx	New test case no-react-query-import with TSX parser validates that a simple React component without React Query imports passes through unchanged.

Poem

🐰 A guard so wise, it checks with care,
If react-query isn't there,
It leaves the code in place, pristine,
No transformation in between—
A simple skip, a quiet pass,
With fixtures bright like morning grass! ✨
