ConnectionThread now calls CaptureService.onNativeExit() via JNI on exit
when g_bExit == S_CLIENT_EXIT (server-initiated). The Java side posts
stopSelf() on the service handler. Guard: instance is null in the
user-initiated teardown path (onDestroy nulls it before nativeStop),
so onNativeExit is a no-op in that case.

- szPCName sent as "model/groupName" format matching Linux client
- CMD_SET_GROUP handler updates g_SETTINGS.szGroupName in memory
- Group name persisted to filesDir/yama_group; survives process restart
- LoadGroupName() at startup overrides build-time patch value if file exists
