HintOverlayHost class abstract

Overlay host — the contract of tour render mechanics.

The controller does not know what the overlay looks like: it only asks to show the machine's current state and hide it on completion. The implementation is HintOverlayEngine. In headless runs the host is absent (overlayHost: null) and tours run without rendering: the machine, timers and diagnostics always work — this is what makes the engine a testable artifact.
