Start (or restart) the Hearthstone coach overlay — four native always-on-top panels (turn advice, HDT-style deck tracker, opponent tracker, coaching lessons) fed by the hearthstone-tracker live feed. Use when the user asks to start/launch/restart the overlay, says panels are missing or stale, or wants the coach's advice shown in-game instead of only in chat. Pairs with hearthstone-live-coach, which publishes the advice this overlay displays.
