- Combatants row whose tokenId matches encounter's current combatant
gets data-chh-current-turn=true, an accent-color border + tint, an
outlined portrait, and a '▶' marker before the name.
- Header section prepends '▶' before the turn name.
- buildRenderContext now resolves currentTurn from the encounter
singleton (encounter.currentTurn / encounter.combatantId) instead
of reading game.combat directly. battle-focus owns the encounter.
- Tests: 46/46 in <1s, new section L covers the indicator.
