pushCapable property
Whether this device has a usable push channel — i.e. it has registered a push token with a push gateway and conveyed the resulting opaque WakeHandle to its VTA via device/set-wake (https://trusttasks.org/binding/push/0.1). Informational visibility for device/list only. The raw platform push token is held ONLY by the gateway; the maintainer/VTA holds the opaque WakeHandle and the VTA-owned trigger allowlist, never the token. Set from the presence of a current WakeHandle for this device.
Implementation
final bool? pushCapable;
