* Coverage for [AndroidScannerViewModel.requestBonding]: only a successful bond arms the transport. Bond failures

* surface a warning and wait for an explicit retry so the Android pairing flow does not immediately re-enter through

* transport-side bonding.

*

* Robolectric is used only because the class under test lives in `androidMain`; the bonding outcomes themselves are

* injected via [org.meshtastic.core.testing.FakeBluetoothRepository], keeping each assertion deterministic. The real

* `AndroidBluetoothRepository.bond()` branches are covered separately by `AndroidBluetoothRepositoryBondTest`.
