/**
 * Handles a single assistant invocation. There is no voice UI in v1 — every
 * trigger (long-press Home / corner swipe) simply opens the app in the
 * foreground, then closes the session.
 *
 * [onShow] fires for every invocation; [onHandleAssist] additionally receives
 * the assist data. Both route to the same guarded launch so the app opens
 * exactly once per session. The deprecated 3-arg [onHandleAssist] is kept so
 * the launch works on every supported API level (the framework's
 * [AssistState] default forwards to it below API 29).
