…7343) Summary: The iOS RNTester Maestro suite is flaky because several flows assert the landing screen immediately after `launchApp`, with no wait. On a CI simulator the JS bundle hasn't rendered yet when the assertion fires, so flows fail with `Assertion is false: "Components" is visible` (e.g. `text`, `modal`) or fail downstream after entering through the shared launch helper (e.g. `pressable`). It is a race, not a deterministic failure — `flatlist`/`button` use the same pattern and pass on faster runs. Replace the bare landing-screen `assertVisible` with `extendedWaitUntil` (30s) so the bundle has time to render: - `helpers/launch-app-and-search.yml` (`Components`) — the shared entry path for `text`, `pressable`, `image`, and the new image smoke-test flows. - `modal.yml`, `flatlist.yml`, `button.yml` (`Components`). - `legacy-native-module.yml` (`APIs`). `extendedWaitUntil` returns as soon as the element appears, so this adds no time on the happy path — only headroom on cold start. This is the actual fix for the red iOS E2E; the earlier `spawnSync ETIMEDOUT` was the suite failing + retrying + occasionally overrunning the 10-minute per-attempt cap, not a simulator/driver-startup problem. No harness/setup changes. Changelog: [Internal] Reviewed By: cortinico Differential Revision: D109742688
