Three new rules. Nothing under `domain/` may name `android.content.Intent`, so the validator stays testable without a device. The `AlarmClock` action strings may be named only under `domain/interop/` and `interop/`. And `AndroidAlarmScheduler` may not name `AlarmRingActivity` — the defect this milestone fixed would otherwise come back the next time someone reaches for a "show the alarm" intent.
