fix(ci): drop 'home' step from smoke test so compile step finds Settings

The smoke test's final 'home' step navigates FakeMirroring back to the empty home screen, so the next workflow step (compile skill) opens with no app foreground and its 'wait_for: Settings' times out. The smoke test's purpose is to validate the runner against Settings; testing the home key is incidental and can land in its own dedicated skill later if needed.
