/**
 * The state-toggle `DeviceSource` (design.md D19; tasks 6.8–6.11).
 *
 * Promotes a `StateManager` boolean toggle to an ordinary device: its stable
 * identity is the state key, its capability is one writable boolean, and its
 * liveness is push-backed and always reachable, since its backing store is
 * in-process. Toggles are declared explicitly; the source never derives them
 * from the contents of the state store, so keys the engine writes for its
 * own purposes — room assignments, automation enabled flags — are never
 * presented as user-facing devices. This holds whether or not the HomeKit
 * bridge is enabled, since this source has no dependency on it.
