BluetoothCollector

Reports Bluetooth availability/enabled state, bonded-device count and paired-device class distribution via BluetoothManager. The bonded list requires BLUETOOTH_CONNECT; without it counts are reported as zero.
Privacy: the set of paired accessories is identifying; device names/addresses are never exported, only class counts. Gated behind PermissionKind.Bluetooth.
