HintMachine class

Pure tour state machine — all transition policy in one place, zero widget imports and zero knowledge of the registry/overlay.

The only external dependency is the injected targetPresent predicate on dispatch, by which the machine decides: advance straight to the active step, or go into waiting for the target. In tests this is a presence map; in the controller it is registry.lookup(id) != null.
