Subject: [PATCH] fix: call ContextualSearchManager wrapper so CSService works
 on Android 17

Android 17 added a ContextualSearchConfig parameter to
IContextualSearchManager.startContextualSearch and removed the
single-argument form, so the direct Binder reflection call failed with
NoSuchMethodException and Circle to Search never opened.

Call the framework wrapper ContextualSearchManager.startContextualSearch(int)
instead. It exists on Android 15, 16 and 17 and builds the Binder call with
whatever arguments the installed platform expects.
