heartbeatEnabled

Whether the location-tracking heartbeat is enabled for this install.

The heartbeat ships disabled by default — a deliberate privacy design: "the host has OS-level location permission" is not the same as "the host's user has consented to a continuous live location signal being sent to the AFCore backend." Set it through Builder.heartbeatEnabled; this is the supported replacement for the deprecated AFCore.setHeartbeatEnabled.

Reads back false both when the host explicitly disabled the heartbeat and when it never declared a preference on this config (in which case the SDK keeps whatever per-install choice was already persisted). To distinguish those two cases internally, the SDK uses heartbeatEnabledInternal.
