Subject: [PATCH] test(mobile): census native-only APIs over the whole hosted
 graph

The binding test banned Clipboard.setStringAsync, Linking.openURL and
router.push('/terminal-settings') over a 42-file list, so injecting all three
into MobileTerminalInputActions.tsx passed. The census walks the 1052 modules
the hosted session route actually reaches and catches it.

AsyncStorage is deliberately excluded: it is genuinely reachable from the hosted
bundle today through the shared storage and transport modules.
