CellGuard app: on-device IMSI-catcher detection (Kotlin/Compose)
- foreground DetectorService: cgcap capture + on-device decode - framework CellInfo source: real serving+neighbor towers, signal, carrier name - FrameDecoder: 0x070F cell-info SIT decode - block-2G/3G + detection toggles via cgctl; libsu root bridge - silent status notification + edge-triggered alerts
