/**
 * Emulator-QA probe: does the autofill framework issue fill requests for a
 * native form at all? Launches [QaFormActivity] in the TEST package (a
 * different package from the Peach autofill service, so the framework will
 * fill it), taps the username field, then reads `dumpsys autofill`
 * (shell-priv via UiAutomation) and asserts a session mentions the test
 * package. If this fails, autofill is blocked emulator-wide; if it passes,
 * a Chrome-specific problem is confirmed.
