// TestPreferUserEventSetupIgnoresSetupCall verifies testing-library prefer-user-event-setup: setup calls are not reported.
//
// Locks the distinction between creating a user-event instance and invoking an
// interaction method. The rule should ask direct event calls to use the setup
// result, not flag the `userEvent.setup()` call that creates that result.
//
// 1. Import the default user-event object.
// 2. Call `userEvent.setup()`, then mix a direct user-event call with a setup-result call.
// 3. Assert only the direct interaction is reported.
//
// @evidence contracts/testing.md#behavioral-verification The owning engine and Testing Library assertion helpers verify only the direct userEvent.click reports while setup and user.click remain clean; exact normalized findings reject extra or missing results.
// @evidence contracts/testing.md#independent-expectations setup creates the supported interaction instance; creating it is not an event operation.
// @evidence contracts/testing.md#distinguishing-cases The same source contains setup creation, direct interaction and setup-result interaction, separating all three shapes.
// @evidence contracts/testing.md#execution-ownership TestPreferUserEventSetupIgnoresSetupCall assertTestingLibraryFindings parses the source as TSX under a virtual component.test.tsx path and runs NewEngineWithResolver over it with only prefer-user-event-setup enabled and requires exactly one triple, at the direct userEvent.click line, while the setup calls and the setup-instance click stay unreported. No DOM runtime, installed consumer, native build or product child host runs.
