// TestPreferScreenQueries verifies testing-library query style: render-result queries should use `screen`.
//
// Pins both render-result shapes supported by the AST-only analyzer: destructured
// query functions and method calls on a variable assigned from `render`. Both are
// high-confidence because the local names come from the `render()` expression.
//
// 1. Import `render` from Testing Library.
// 2. Call a destructured query and a query method on a render result variable.
// 3. Assert `prefer-screen-queries` reports both calls.
//
// @evidence contracts/testing.md#behavioral-verification The owning engine and Testing Library assertion helpers verify destructured and member queries from render results both report; exact normalized findings reject extra or missing results.
// @evidence contracts/testing.md#independent-expectations screen owns the shared query API rather than each render result.
// @evidence contracts/testing.md#distinguishing-cases Both reported binding forms differ from a direct screen query. The original violations remain intact and the authored adjacent source is asserted clean.
// @evidence contracts/testing.md#execution-ownership TestPreferScreenQueries assertTestingLibraryFindings parses the source as TSX under a virtual component.test.tsx path and runs NewEngineWithResolver over it with only prefer-screen-queries enabled: the destructured-query and render-result-member source must yield two exact triples and the screen-query source must yield none. No DOM runtime, installed consumer, native build or product child host runs.
